Can you abstract the hard-coded boot path /boot to a variable so that it can be changed in one place instead of half a dozen?
I'm using GRUB EFI with some other OSes and this is requiring a lot of hacking.
ssh-keygen gets installed with openssh-client optional package. If openssh-client is not installed, regenerate SSH host keys fails at boot with the following message.
Starting Regenerate SSH host keys...
[FAILED] Failed to start Regenerate SSH host keys.
See 'systemctl status regenerate_ssh_host_keys.service' for details.
If ssh-keygen is not installed, it is safe to skip regenerating ssh host keys at boot.
raspberrypi-sys-mods postinst appends audio settings to /boot/config.txt. If the existing config.txt uses hardware-specific sections ([pi3]
, etc) then those changes will only be applied to whatever hardware section was last active, not globally.
It should probably append an [all]
before the audio changes.
Hi,
is there a specific reason, why there is no LICENSE, COPYING or similar declaration (lone SPDX-License-Identifiers in each file probably do not suffice) stating under what license the content of this repository is published at github?
As i understand law, the current form of publication makes it open source but not free open source, meaning that any modifications i might make are in almost all cases prohibited to be shared with others.
So that's the question: why are the current state of affairs as they are?
best regards,
Max
Problem:
The sshpasswd.sh script in etc/profile.d performs the check even if the current user is not able to perform the sudo action required. This triggers a security notice (and in my case an email).
Mitigation:
A possible solution would be to check the "$USERNAME" variable for equality with "pi"/"root" before calling "check_hash".
I can prepare a Pull Request if necessary.
Continuing from #1:
Hello, after today upgrade to new version of raspberrypi-sys-mods and reboot I'm getting huge fps drops from motion detection camera connected to RPi 3 even I did upgrade to raspberrypi-sys-mods_20160916_all.zip from this thread with dpkg.
The second RPi 3 with camera and without upgrade works fine. Any suggestions please? Thanks.
Hello,
On every login, mkpasswd complains about wrong salt length:
Wrong salt length: 0 byte when 8 <= n <= 16 expected.
This is caused by the new sshpasswd.sh in /etc/pofile.d/ on line 10:
HASH=$(mkpasswd -msha-512 raspberry "$SALT")
I think there's something off with the sed line that results in an empty $SALT variable. At least, you should check $SALT for emptyness before passing it to mkpasswd.

Instead of echoing into files, you should use conffiles
to allow dpkg to do the versioning management.
This is how it should be made :

with installed raspberrypi-sys-mods the error message "-bash: gettext.sh: Datei oder Verzeichnis nicht gefunden" comes up after successful login.
("Datei oder Verzeichnis nicht gefunden" translated to english: File or directory not found )
tracked the message down to /etc/profile.d/wifi-country.sh where in line 4
the file gettext.sh is sourced:
(

. gettext.sh
I'm running kernel 4.19.8-v7+ on a Pi 3B+ (from BRANCH=next rpi-update
). When running systemctl status
, I noticed that the system was in a "degraded" state. Running systemctl list-units --failed
showed that the failed unit was the wifi-country.service
unit.
That service runs /usr/lib/raspberrypi-sys-mods/wifi-country
, which performs the following logic to get the WiFi iomem address:
address="$(/bin/grep -m 1 /mmc /proc/iomem | /usr/bin/cut -f1 -d-)"
The contents of /proc/iomem
look something like this:
root@raspberrypi:~# cat /proc/iomem

That grep for /mmc

Still I don't know where you are about this problem, ill keep suggest new possibility.
This one would be to separate the management of the file /etc/apt/sources.list.d/vscode.list and the related key management in a separate package that do one thing (adding M$ repo) and do it well.
Hi,
According to the official blog there is following statement:
Over half of the seven million Raspberry Pi units we sell each year go into industrial and commercial applications, from digital signage to thin clients to process automation.
Most industrial applications use the os lite version with no desktop interface at all and are behind a firewall that monitor the connections. When an OS pushes a package update and without user permission, install some trusted keys and create new hits on the firewall that require an ITSEC investigation, well, this has nothing to do with the industrial domain. Basically CM4 module remains out of scope in my opinion and the only way to recover the lost trust is to have an LTS version with the guarantee that no bloatware will be added. Connections management is a must for today security standards, security devices trigger an alert or totally block a device if unexpected traffic is detected as the device will be considered compromised.
Things are even worse because I had not seen any acknowledgement that this was a bad decision, but instead comments to previous issues are blocked and some of them are even deleted.
PS. I know I can delete these two files, but imagine you need to do this on dozens devices.
Hi,
Super-minor issue to report; there's some .DS_Store files leaked into the raspberrypi-sys-mod package in the following locations:
/usr/.DS_Store
/usr/lib/.DS_Store
/lib/.DS_Store
/lib/udev/.DS_Store
I can't actually see those files in the git repo so presumably an issue in packaging?
Anyway... totally a non-issue, which I wouldn't bother to mention except... OCD!! :-D

If the user disables wifi in config.txt before setting the country they will still see the message "Wi-fi is disabled because the country is not set." on logging in. However, they will be unable to set the country using raspi-config, because it will detect that the wifi is disabled by the user and refuse to set the country.
Why not replace microsofts repository by the vscodium repo since this is probably done for cash, since its pushed onto people without an obvious warning. There were obvious other free options but they chose not too? Why?
For the last few drops I have noticed that each time raspberrypi-sys-mods
gets an upgrade as part of a system apt-get upgrade
, the RPF touchscreen goes black. I have also experienced that over HDMI feeding up a lapdock (standard HDMI displays are unaffected).
Today I went back to an earlier Raspbian image just to test the theory that raspberrypi-sys-mod
was the culprit, and confirmed it is. In fact I can produce the problem on demand like so:
sudo apt-get remove raspberrypi-sys-mod
sudo apt-get install raspberrypi-sys-mod
The call to fix_partuuid here ->
Could you possibly wrap this call within an "If Not 'NOOBS'" condition?

The new version of raspberrypi-sys-mods is trying to install systemd and I'm not sure why this is necessary.
Depends: init-system-helpers (>= 1.18~), libcap2-bin, systemd (>= 230)
Is there any way around this as I'm not keen on installing systemd at all.
$ bash -x -l
[...]
+ for i in '/etc/profile.d/*.sh'
+ '[' -r /etc/profile.d/sshpasswd.sh ']'
+ . /etc/profile.d/sshpasswd.sh
++ service ssh status
bash: service: command not found
++ grep -q running
++ unset check_hash
The new sshpasswd.sh expects the executing user to have sudo without password rights, if that is not the case at least in my setup (which is pretty much default, besides the user configuration) it will send an email warning about security issues.
On one of my machines that is triggered by connecting via ssh, on one other it is actually triggered by an init script of one of the processes. In the first case it just fails with "a password is required", in the second case it warn that "user X is not in sudoers".
In itself that is a quite useful feature, but I might not be the only one who gets confused if systems send you emails warning about someone grepping in your /etc/shadow file.
By moving the entry for the pi user to /etc/sudoers.d/010_pi-nopasswd, passwordless sudo for pi is reintroduced even if it has previously been removed/disabled. I would consider that a security issue.
IMHO, the file should only be created if a) the original entry is still in /etc/sudoers and b) the user pi still exists.
Thanks for this very useful package.
I noticed that cmdline.txt
serial interface replacements may not catch situations where both console=ttyAMA0
and kgdboc=ttyAMA0
exist.
Is it intended?
Should only the first one be replaced, and not kgdboc
?
Thanks for your thoughts.
PS: also unsure why whois
dependency is required
/etc/profile.d/sshpasswd.sh assumes that any user logging in via SSH is allowed to run the command
sudo -n grep -E '^pi:' /etc/shadow
That assumption is just plain wrong.
Recently pushed commit 655cad5 adds Microsoft repo to /etc/apt/sources.list.d
, as well as /etc/apt/trusted.gpg.d/microsoft.gpg
. Why is this actually needed?
Hello,
I found out that when you generate an own Raspberry Pi Image with pi-gen you will not have and get any Microsoft Repository. Because at the moment you only add the Microsoft repository if the raspberrypi-sys-mods version is lower than or unequal to the current version.

Hi,
My dev box received an update of raspberrypi-sys-mods numbered 20210125 from raspberrypi.org
signed by โ Serge Schneider Mon, 25 Jan 2021 16:03:24 +0000
But I don't find it anywhere in :
https://github.com/RPi-Distro/raspberrypi-sys-mods/blob/master/debian/changelog
Im confused, is this voluntary ?
Following 4.19.40 and newer and improved driver, maybe one can remove related blacklist?
FIRSTBOOT does some partition checks, in particular that the root partition is the last partition and is on the same device as the boot partition. I assume these are to prevent needlessly resizing the root partition for NOOBS/PINN. However, this causes firstboot to exit completely and it does not do any of the other tasks such as ssh key generation or OS customisations. I think it should just prevent the partition resizing, but continue with the other tasks, or am I missing something?
(whilst OS customisations would not be applicable from rpi-imager, these files could be produced from other tools.)

Every service has at least four entries of one type, but then also there are additional practically identical but differently formatted blocks for the same services. Something went wrong with the debhelper execution it seems, but since I don't use debhelper, I cannot say what ๐.
I don't use vscode. I will NEVER use vscode. I run my raspberry pi headless as a DNS filter for an education environment. (Where we use libreoffice.) I only access RPi via ssh over openVPN.
How do I instruct apt to remove vscode.list and other trojans, such as /etc/apt/trusted.gpg.d/microsoft.gpg (that seem to have appeared on my devices without my request)? [Seem ironic to have a corporation's key inserted into "trusted" when this just confirms that they can't be - double irony for me reporting here on github.]
I would also like to know the best way to prevent ANY Microsoft files being inserted into /etc on my linux operating system. (Feels worse than a root-kit.) While I sensibly and calmly investigate the potential impact of migrating to either archlinuxarm or FreeBSD.
The sshpasswd.sh script does not handle the salt correctly if the password string for the pi user contains rounds=...
in the hashed password string.
Use case:
In this case I am configuring the pi user with Ansible and using a crypted password generated using passlib for python as described in this doc http://docs.ansible.com/ansible/faq.html#how-do-i-generate-crypted-passwords-for-the-user-module
This results in the following line in /etc/shadow: pi:$6$rounds=656000$salt$password...
Since sshpassword.sh does not expect this, it returns 'rounds=65600' as the SALT on line 9 and displays the following error when executing line 10:
Illegal salt character '='.
The above error appears to cause HASH to be an empty string which exits the script at line 11
Suggested solution:
Something along the lines of this should fix the issue:
if echo $SHADOW | grep -q "pi:\$6\$rounds\="; then
SALT=$(echo "${SHADOW}" | sed -n 's/pi:\$6\$rounds\=[0-9]*\$//;s/\$.*//p')
else
SALT=$(echo "${SHADOW}" | sed -n 's/pi:\$6\$//;s/\$.*//p')

From the latest Raspberry Pi OS Lite image, the content of /boot/cmdline.txt
before running firstboot
is:
console=serial0,115200 console=tty1 root=PARTUUID=544c6228-02 rootfstype=ext4 fsck.repair=yes rootwait quiet init=/usr/lib/raspberrypi-sys-mods/firstboot
If I am not wrong (according to this) the string quiet
is removed only if the string splash
is found. However, given the file mentioned above quiet
appears to be removed anyway, infact after first reboot the content of cmdline.txt
becomes this:
console=serial0,115200 console=tty1 root=PARTUUID=544c6228-02 rootfstype=ext4 fsck.repair=yes rootwait
Knowing that the exit status of grep
is 0 when a match is found and that such value is interpreted as a success in an if
statement, shouldn't the negation be removed from the following line?
What am I missing?
In the Debian-maintained Buster package for RPi.GPIO, the package maintainer has included the udev rules in the 'rpi.gpio' debian package. It uses the 'dialout' group rather than the 'gpio' group. Could there be a conflict with 'raspberrypi-sys-mods/etc.armhf/udev/rules.d/99-com.rules'? It suspect it will cause a lot of confusion with end users following existing guides found around the web. A good example would be when the user has added the 'www-data' user to the 'gpio' group so that website scripts can use gpio.
Hello
I have headless pi and do not want vscode or any Microsoft products.
How can I remove it?

It looks like /boot/custom.toml
is applied on firstboot, but if I have an SD card of an existing image, and move from one location to another and want to update the wifi, can we have /boot/custom.toml
apply on every boot?

In my humble opinion, the file /etc/sudoers.d/010_pi-nopasswd should be removed or changed. Since the last release, the pi user is no longer a default user (ref: raspberry-pi-bullseye-update-april-2022).
Maybe I didn't got it, how it should work then I would appreciate any explanation.

There appears to be a bug in the assignment of the primary and secondary serial ports in bookworm.
It looks like a problem in:
raspberrypi-sys-mods: /etc/udev/rules.d/99-com.rules
When bluetooth is disabled in config.txt as:
dtoverlay=disable-bt
I would expect that
/dev/serial0 -> ttyAMA0
/dev/serial1 -> ttyS0
and this is what bullseye does, correctly, but instead with bookworm we see:
/dev/serial1 -> ttyAMA0
and /dev/serial0 is not symlinked at all.
This is contrary to the advice here:
https://www.raspberrypi.com/documentation/computers/configuration.html#primary-and-secondary-uart
and looks like a bug in bookworm :)
Original issue: raspberrypi/rpi-imager#581
If the user enters a SSID in Imager's advanced settings that contains a $ and writes RPI OS, /etc/wpa_supplicant/wpa_supplicant.conf does not get written correctly.
Imager correctly writes a firstrun.sh that calls: /usr/lib/raspberrypi-sys-mods/imager_custom set_wlan '$1234' 'somehash' 'GB'
And that should work because the shell does not see it as a variable if the $ is inside single quotes.
But your script in turns seems to write out a set-wlan helper script that contains: if raspi-config nonint do_wifi_ssid_passphrase "$1234"
And with double quotes $1 does is seen as variable.
Probably also gives problems if the SSID contains a " but haven't tried.
Would be great if you instead of pinpointing a user in 010_pi-nopasswd you instead
pinpoint a group for example like this:
010_rpi-nopasswd:
%magicwand ALL=(ALL) NOPASSWD: ALL
as user pi anyway in my case its the first i remove from raspbian and create my own, so
hopefully you would consider altering this to a group policy instead of user policy.
I have allready made my quick and dirty deb package with the correct settings for this however i feel its much better if upstream version of raspberrypi-sys-mods would have this feature instead so i dont have to lock
my version as the one system would prefer :)

Since c8a2ee7 you are using "uuid" in imager_set_custom
There are end-user reports suggesting that is MIA in RPI OS Lite: https://forums.raspberrypi.com/viewtopic.php?p=2165884#p2165884
The abovementioned file contains an echo statement which is apparently not adequate in a sysctl.conf file. Consequently, starting systemd-sysctl.service via "systemctl start" produces an error message. The second line in the file should probably read
vm.min_free_kbytes = 16384
On a further note, this settings conflicts with "vm.min_free_kbytes = 8192" found in /etc/sysctl.d/99-sysctl.conf under "rpi tweaks".
Hey there,
Please forgive me if my english isn't the best, I am no native english speaker.
I am one of the MainsailOS maintainers and some users reported an Issu that our latest Image hangs on the first boot while Generating SSH Keys ...
is running.
After a bit of research I identified the root cause in the fix_partuuid
function of first boot script.
To come them by I commented out the whiptail lines and added set -ex
to see whats going on.
As you can see it struggles to do the step. I waited for around 20minutes on a Pi Zero 2 W without being successful.
To prove the issue please use our latest image using rpi-imager
.
As proof of concept for that script you can use an artifact of my patched version from here:
https://github.com/mainsail-crew/MainsailOS/actions/runs/4515245620
But I think you can also reproduce it with pi-gen using the latest kernel instead of kernel 5.15y which is currently shipped in rpi-imager
I will open a PR on that, to prevent you are running into that issue with future releases of Raspberry Pi OS.

Would it make sense / be possible to change etc.armhf to just be etc so that it is installed on both armhf & arm64? Or alternatively just create a separate etc.arm64 subtree alongside the etc.armhf subtree for the files that work just fine on arm64?
For instance the etc.armhf/udev/rules.d/99-com.rules file definitely works on arm64, and is required to setup the serial device node so that the Bluetooth uart device scripts work in arm64 installed on the 3b+.
