Weirdness with getwd(3) in loopback filesystem

[Bob Weissman]

Thanks to those of you who responded to my question why "mount -t lo ..."
didn't work from within /etc/rc.  It works fine after adding the missing
"export PATH" statement so that "mount" can find "mount_lo".

But it appears that getwd(), as shown by /usr/bin/pwd, can't handle
loopbacks.

    % mount | grep -v nfs
    /dev/sd0a on / type 4.2 (rw,nosuid)
    /dev/sd0g on /usr type 4.2 (rw)
    /dev/sd0h on /var type 4.2 (rw)
    /var/tmp/tmp on /tmp type lo (rw)

    % cd /tmp	<-----------+
		            |
    % pwd		    |
    /var	<-----------+

    % dirs
    /tmp

Very interesting!
