Ugh, netfs_attempt_lookup did not fail, but netfs_S_dir_lookup does!  This
is because it sees that S_ISCHR evaluates to true on the node.  Because
fakeroot has no translator started on the node yet, fshelp_fetch_root will
try to do so.

Of course, it is not allowed to start a translator (whatever type of
translator it wants to start, I didn't check which, maybe even "chrdev") as
root (which is still the owner of /server/socket/1), so fshelp_fetch_root
fails with EPERM.

Distress.  What can we do?  Override... netfs_S_dir_lookup?
fshelp_fetch_root?

Thanks,
Marcus
