I have a PC here that I multi-boot between multiple distros (around 64GB each).
It’s currently setup in a way that I don’t want to share the whole /home due to avoiding messing up the ~/.config or any other dot directories in there, so the “shared home” is mounted on /mnt/home
Right now, I got it to share /var/snap, /var/lib/snapd, /var/lib/flatpak and /snap as Btrfs subvolumes, and it’s working well. For Flatpak, I have ~/.var symlinked to /mnt/home/<user>/.var
Since symlinks don’t work, is there another option I can use other than binding via /etc/fstab?
Note: all the stuff are local to the PC, not via NFS (though that would be really nice if it can be solved already).
