allowing mount options -- bad idea: e.g. suid	
	allow/deny:
		currently using strcmp, but what about uid=XX type options?
		
honor -pX rather than just p0

have mode of not waiting for mount to finish
automatically include required options in allow

DONE
----
options_allow, options_deny, options_require
~/.pam_mount.conf don't work
	fstat: No such file or directory
	File ~/.pam_mount.conf could not be stat'ed
	use getpwnam to get home dir right

permissions checking for local mounts
	--> check for ownership on mount source
		--> only if from user config

verify that local mount security works

security hole:
	no, must specify _some_ mount source
	can't get mount source which is
		1. owned by user
	and	2. acceptable to mount commnd as no-op

[global config]
volume user1 local - /dev/hda123 /home/user1 -

[user config]
volume user1 local - - /home/user1 remount,suid
