I'd love to try it, but the install is pretty involved, and the instructions are hard to find and haven't found any that are linux specific and provide paths for content locations.
I think the tricky file to find was ~/.config/openmw/openmw.cfg and it needed to che changed to include:
fallback-archive=PT_Data.bsa
fallback-archive=TR_Data.bsa
and content=Tamriel_Data.esm
Then everything else was managed with the openmw-launcher UI. The game ended up installed in ~/.local/share/openmw/ with some funky setup to deal with mods.data="/home/user/.local/share/mw/Tamriel Data (HD)"
data="/home/user/.local/share/mw/Tamriel Rebuilt"
