When you specify a directory where a map will be mounted in auto.master,
if it does not exist, autofs will create it upon startup and remove the
directory when it shuts down. However, if the directory already exists,
autofs will still remove it when you shut down. I've attached a patch
to autofs-4.1.3 which will prevent autofs from removing previously
exisiting directories.
If you have any questions, let me know!
Thanks,
Chris
