Using Arch with ZFS as rootfs here and I encountered a pretty annoying problem.
It appears that Steam is unable to recognize my datasets as usable space as it throws an error message, telling it needs 250 MB of disk space in order to update. I tried creating a zvol which I formatted with ext4 and mounted it at
/mnt/steam. Then I symlinked the Steam files to that location but that couldn’t fix the problem.
This prevents me from testing my game library against Proton on bare-metal. Any idea what else I could try?
