i have small ssd and larger hdd on debian and play a few games on it. the games are 30-50+gb ea. they stay on the hdd with the wine files (prefixes/runners). i’m not gonna move that crap around constantly just to play, and i can then use btrfs on ssd more easily. no need to worry about disabling cow on certain game directories, or making different subvols so snapshots aren’t massive.
