If you use the libsurvive driver then you'll need to persist the lighthouse calibration data. If you use the SteamVR LH driver (which is non-free but much better) you'll need to persist $XDG_DATA_HOME/Steam/config (I think, that's where SteamVR stores its lighthouse calibration)

I do have .local/share/Steam persisted already https://git.disroot.org/tumble/linux-config/src/commit/e26b06edf618224040d679dfd4edff3d56bcc308/modules/home/gaming/default.nix#L33
