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? -Steve
