first hitch: the file server can't find the ZFS kernel modules. probably because i ran an update at some point before shutting it down but never restarted it, so the modules didn't get put in the right place? who fuckin' knows, i'm trying that.
this is going to be somewhat of a temporary setup that's living at a friend's house for a bit, so i can't rely on the assumptions of my previous home network. which had kerberos authentication and an entirely separate machine from the file server solely to be a hypervisor. plex itself runs on a separate NUC with an eGPU, because i simply cannot ever build a network that isn't at least a little distributed.
