Since I used the default partition layout, /boot/ is part of / and needs to be readable by GRUB. Unfortunately GRUB stable cannot yet read zstd compressed btrfs partitions (support has been added in git already: https://git.savannah.gnu.org/cgit/grub.git/commit/?id=386128648606a3aa6ae710...).
My question is: is it safe to compress other subvolumes of /, like /var?
Should be safe.
Good to know, thanks!
And would it be safe to put /boot/ into an uncompressed subvolume and compress everything else (including /)?
Putting /boot into a subvolume will break snapshots, rollback, ... But you don't need to do that, if I remember correct, you could compress the files in /boot with another algo or not at all, without the need to put it into an own subvolume.
I can compress everything except /boot/ manually, but according to my understanding btrfs will not automatically compress new files, unless I mount it with compress=$algo (which I don't want since /boot/ will be then also compressed on the next initrd rebuild). Is there a way around that?
