>Description:
	It is impossible to remove dotfiles on shares mounted with shlight.
>How-To-Repeat:
	Mount an SMB share:
	sun:~# shlight //blackhole/music /mnt -W INVISIBLE -U jmcneill -C
	Password:
	Using port 64390 for NFS.

	From here, touch a dotfile (touch /mnt/.me) and try to remove it
	(rm /mnt/.me) and you will get permission denied.
