Hi,
I've just tried to move .var using symlinks which didn't really work for some apps, Spotify still worked Steam didn't.
bwrap: Can't make symlink at /home/x/.var: File exists
Sylinking .local/share/flatpak onto the other filesystem did't help either, after doing some research I discover that it is possible to move the installation(the app it self) but apparently not it's data(.var).
So just wondering if there is actually a way to move .var or even better just one app's data onto a different filesystem?
https://github.com/flatpak/flatpak/issues/1224 might be of interest
Already tried that but the problem is that the games steam downloads are part of the application data and not part of the app package/executable env itself and .var is always located in $HOME irregardless of the apps installation location.
Try to bind it using fstab. Steam works for me with something like this
/opt/flatpak /var/lib/flatpak none rw,defaults,bind,noatime,nodiratime 0 2
I have never used per user installations so sorry if that's no relevant to your case.
I don't think there is anything fo ruse to do there
