Duh. Reload only checks for changes in the auto.master file. Sorry for
the noise.

Did the script return success when you issued the stop? My guess is it
just didn't wait long enough for the umount? Just a guess.
Anyway, I've got some changes to the redhat side of the autofs script to
change the status it prints out (to reflect reality). Perhaps the attached
patch is worth including?
It may even be beneficial to change autofs reload to send a HUP to all
automount daemons. Ian, what do you think?
Cheers,
Jeff
