theres a bootstrap problem:
when /bin/init is run, it processes /lib/namespace where we might want to
mount or bind resources to /n or /mnt. but mntgen was run later in
cpurc/termrc so these mounts would be ignored.
we already have mntgen in bootfs, so we can provide these mountpoints early.
i keep the termrc/cpurc mntgens where they are, but ignore the error
prints. this way old kernels will continue to work.
this makes sure tcp boot will have ther user /tmp's
the same way as from local cwfs. we used /srv/cwfs
to prevent a deadlock with 9660srv as a root filesystem
which has been fixed now.
