I’m using debian 13 and the (default?) mount options are:
/dev/mmcblk1p2 on / type btrfs (rw,noatime,compress=zstd:3,ssd,discard=async,space_cache=v2,subvolid=5,subvol=/)
Seems like the needed barrier option is on by default, but maybe I miss something?
The goal is to have it survive random reboots once a while without any intervention (e.g. fsck asking to press ‘y’ on the console after an unfortunate reboot)
Should usebackuproot be added? Or just rescue=all?
The proper way would be to have a read-only / with /var and other stuff on a separate volume, but perhaps with current filesystems this isn’t needed?
Thanks.
