I’m trying to create subvols on Btrfs to exclude snap applications from snapshots/recovery, but I’m having problems:
I have already created the subvols on the folders:
With these folders created on restore I find all the applications installed even after a restore; snapshot btrfs > snap install telegram-desktop > restore snapshot btrfs
But when I start the application I have this error: error: cannot find installed snap “telegram-desktop” at revision 994: missing file /snap/telegram-desktop/994/meta/snap.yaml
From what I understand why I have not excluded from the snapshot also: /etc/systemd/system/multi-user.target.wants/
But if I exclude this folder too, I have no risk of starting other applications/services that I have previously uninstalled? Am I wrong?
With flatpak it was enough for me to exclude this folder /var/lib/flatpak
This is my fstab: https://paste.ubuntu.com/p/Yh9Bk5ZFgY/
