gentoo. i’m not even gonna look this up but i’d be surprised if immolo hasn’t installed in that platform yet ;)

You can get this as a snack in Taiwan, broken instant noodles with seasoning ;)

LGR has a nice review of this and a similar machine: https://piped.video/watch?v=6bODiZ5bP84

I can’t really tell you what to use, but from my personal experience - stay away from glusterfs and drbd. both have caused me serious trouble when trying to run them in a production setup. ceph seems to be pretty solid, though.
