BTRFS snapshots on GRUB for Debian/Ubuntu-based distros

[KorraHarraway]

Hi,

I would like to know if by executing the makefile script (or moving manually the files) is it possible to install the feature into the GRUB (of course, for btrfs installations with subvolumes already properly set in FSTAB) of latest Debian and Ubuntu-based (20.04+) distros.

If possible anyway, how should I proceed?

Tks in advance :)

On Ubuntu, you can follow the instructions for manual installation from the README, (via make).

This should work for Debain too, although I'm not absolutely sure if there are any dependencies which are on too old versions in the repos.

Once the script is installed, configure it to your needs via /etc/default/grub-btrfs/config, and run update-grub. If you want automatic GRUB updates after new snapshots are made, run systemctl enable --now grub-btrfs.path. Depending on your snapshot location, you'll need to edit this unit file beforehand.

That's documented in the README though. Wish you success, cheers !

Tested and it is working here :)
