Sure.

This is auto.master:
/home	/etc/auto.home

This is auto.home:
aaron	:/srv/home/aaron

This is the syslog with the -d option to automount.  Below you'll see me
sending a USR1 signal to the automount process, but the umount not
happening.  After this I just umount /home/aaron by hand and then stop
automounter...
