Not mounting any target about zram-config HOT 4 CLOSED

Alright, I am not surprised that you have had issues with this. First off, RPi 4 8GB does not always work correctly with zram right now. This is due to a Linux Kernel issue that is ongoing. While not a part of this project, this post on the openHAB forum has some details. For the moment there are no real good ways to enable zram on a RPi 4 8GB it may be possible but I won't try and support it as the methods used would be very hacky.

Second, it should not be necessary to put the /tmp directory on zram please read the Performance section of the README to get more details.

I will make sure to make a note in the README so that people know that the RPi 8GB is not currently working with zram due to this issue.

Aaahh, I see, I didn't even think about that, lol.

I saw this section but my /tmp is not mounted in RAM but in the root.

domy@domy-pi:~$ df -h /tmp
Filesystem      Size  Used Avail Use% Mounted on
/dev/mmcblk0p2  117G  6.4G  106G   6% /
domy@domy-pi:~$

Thanks for your time!

Anyhow, I do have around 5 MB writes per day, it's not that urgent, I'll wait for a fix.

Ahh, well then you would likely be better suited with using /etc/fstab to mount your /tmp directory on ram rather than zram.

from zram-config.

Actually, I've found that tmp.mount is not enabled by default, we need to copy *.mount file and enable it.

sudo cp -v /usr/share/systemd/tmp.mount /etc/systemd/system/ 
sudo systemctl enable tmp.mount

domy@domy-pi:~$ df -h /tmp
Filesystem      Size  Used Avail Use% Mounted on
tmpfs           3.9G     0  3.9G   0% /tmp

So, I will close this issue, there is nothing we can do right now.

Best regards!
