Ah, possibly. Perhaps you could make libnetfs to accept any access when
auth/proc are not available

No, you'd need actual auth/proc servers, which at that point cannot work
since we don't have a FS yet.

? once libpciaccess gets a port on pci-arbiter's root, it can use
file_name_lookup_under to open directories and files in it. libnetfs
will want to check permissions, but it could be made to accept anything
when auth/proc are not available yet.
