It doesn't mount /misc, that's just where the mount points are.

eben@pc:~$ lsof -n | grep /misc
man 6203 eben 6r DIR 8,5 4096 1811521 /misc/export/man
man 6203 eben 7r DIR 8,5 4096 1355173 /misc/export/X11/man
Hm, OK, look for a man page.... found one:
eben@pc:~$ lsof -n | grep /misc
eben@pc:~$
Still won't work:
eben@pc:~$ sudo umount /misc/scratch ; sudo lsof -n | grep -e /misc -e scratch ; sudo /etc/init.d/autofs stop
umount: /misc/scratch: device is busy
umount: /misc/scratch: device is busy
automount 3102 root 5r DIR 0,18 0 6200 /misc
hald 4381 haldaemon mem REG 8,2 171981 121529 /var/lib/misc/usb.ids
hald 4381 haldaemon mem REG 8,3 529991 443185 /usr/share/misc/pci.ids
Stopping automounter:
Couldn't stop automount for /misc done.
eben@pc:~$
The stuff from hald's in there because its path contains "/misc". I don't
know an easy way to exclude it.
