== /dev/null permission resets == 

Applies to 4.x jails only

For some reason that I do not understand at all, the /dev/null node in customer jails, after the system is restarted, often reverts permissions to 0600 ... which is bad, because non-root processes cannot redirect to /dev/null anymore.  In fact, a fair number of server daemons will complain and/or fail if this is the case.

So, after a restart, after all systems have restarted, run postboot, which does something like:
 
 for f in `df -k | grep /dev/vn | awk '{print $6}'` ; do chmod 0666 $f/dev/null ; done

Later, after the system is up, if anyone ever complains about their /dev/null permissions for any reason ... really if anyone mentions
/dev/null in any way, tell them to run:

 chmod 0666 /dev/null

We have ultimately fixed this by adding chmods to the quad/safe's
