I am a little confused by import/export -B (backwards).
The only bit I don't get is why you have to supply a mountpoint to import.
Surely import will always be running from listen and as such it will not
be in any useful namespace so why mount anything?
from the manpage:
Suppose that the machine moscvax has access to a private
file server containing public web pages that need to be
served by the less-trusted server webvax. Webvax runs the
following listener (see listen(8)) on TCP port 999:
#!/bin/rc
import -B -s rowebfs /usr/web /bin/restarthttpd
When moscvax boots, it runs
exportfs -R -r /usr/web -B tcp!webvax!999
to serve a read-only copy of /usr/web to webvax. When
webvax gets the call, import mounts the served tree onto its
own /usr/web and then runs /bin/restarthttpd to restart
httpd(8).
It seems to me that my restarthpptd script will be
'unmount /usr/web; chmod 600 /srv/rowebfs'
I find it strange that the mountpoint is not optional (as long as -s srv names
exists).
perhaps I am missing somthing? or maybe its just a quirk?
