Title says it all - feasible to have the chroot install onto an SD target?

Yep! Make sure the SD card is formatted with some form of ext, then use the -p (prefix) parameter to point crouton to the SD card (usually /media/removable/$label); it will install the chroots to $prefix/chroots and the launch scripts to $prefix/bin. You can then enter chroot either by explicitly using the $prefix/bin scripts, or use the -c parameter to explicitly specify the $prefix/chroots directory when using scripts installed to /usr/local/bin.

Hey.. I created an ext4 partition on my SD. and then I executed:

sudo sh -e ~/Downloads/crouton -t xfce -p /media/removable/External\ Drive/

It started running through, files are in place on the SD but it stopped with the following:

Ah, the space in "external drive" is almost certainly screwing up the part of enter-chroot that remounts the mount with "exec" permission. Looks like they get escaped with \040 in /proc/mounts, so I'll need to compensate for that in the script.

In the meantime, you can manually remount it by running sudo mount -o remount,rw,dev,exec,suid '/media/removable/External Drive' and then try to enter the chroot (it will ask if you want to run the /prepare.sh script, and you should agree).

Okay, that was a stupidly untrivial fix. Anyway, the latest release has it incorporated, so give it a shot. It probably doesn't break everything.

That worked.. Thanks a lot.

I'm just about to test the updated croutonwheel etc and I'll report back..

(I'll deprecate basically all the current guides on my website)

Oh, I think I forgot to mention--if you do install to a different prefix, it's easiest to directly run the chroot scripts from the other prefix, because it'll auto-associate those chroots with it.
E.g. if you install with -p '/media/removable/External Drive', then the easiest way to launch the chroot is simply via sh -e '/media/removable/External Drive/bin/enter-chroot or whatever (note that you don't need the -c this way, since it will assume '/media/removable/External Drive/chroots' automatically).

I tried this on an Asus Chromebook Flip and the performance was horrible when installing a chroot to an SD card, despite it being a top-of-the-line Lexar 600x card. Depends on your Chromebook hardware, I guess.
