Hi there!
Another challenge...
I'm using btrfs. So i make snapshots from my system. And in a script, I
make a symlink (for example: @system.CURRENT and @system.LAST) for the
current and the last snapshot.
So i want to add 2 entries in grub2 from which i can boot into the
current and the last snapshot.
I tried to pass an environmental variable with
systemd.setenv=BOOTSNAP=@system.CURRENT, and i have a mount-unit
containing the option
Options=defaults,nofail,subvol=archive-local/@system.$BOOTSNAP
but it doesn't work. If i change $BOOTSNAP to CURRENT, the mount works.
So i made a test.service, containing only
StartExec=/bin/echo $BOOTSNAP
I get the value @system.CURRENT in the logs...
How can I do this mounts?
