hello,
i've done some searching and i've seen discussion of userland fs
before. has there been any progress in the user-space filesystem area? i
have a nifty project and i would like to avoid using loopback NFS; have we
got anything akin to linux's userfs yet?
if freebsd doesn't have this capability, where would a good place to start
be on loopback NFS? maybe somebody has a loopback NFS skeleton i can start
from?
any pointers/discussion would be helpful.
