You don't need user IDs on your FS, I guess.
Once I get /dev on ramfs managed by udev? Not really, no. I need the permissions to be right, but just about everything else should belong to root. (Yeah, there are a couple fun tricks where files change their ownership to some variant of "nobody" to do chroot jails and stuff, but they do that at runtime...)

NFS is much better, anyway. NFS gives me hives (a stateless fileserver: okay, spot the contradiction in terms here), although I must admit I haven't tried the new TCP/IP based version (V4?) yet because it wasn't finished last time I tried. > And somebody says it's also > faster (and since hostfs does limited caching, it makes sense - hostfs must > avoid having any inode cache, since it closes the host fd only when the > inode is evicted from the cache; I don't think it's possible to cache data > without an inode to link to, so it's clear it's slow). Since the host is cacheing the data for us, not having a redundant cache sounds like a good idea to me. Admittedly, it's more syscalls, but less memory consumption...
