System: NetBSD sasha 4.99.45 NetBSD 4.99.45 (Nocturno-nodbg) #127: Thu Dec 27 03:42:11 CET 2007 juan@sasha:/home/juan/build/i386/obj/sys/arch/i386/compile/Nocturno-nodbg i386

>Description:

	Any PUFFS based file system (and refuse as well) allows to mount
	a file system in the same mount point multiple times, no other
	file system allows that AFAIK.

$ sudo mount -a
$ mount|grep puffs
/dev/puffs on /sysctl type puffs|sysctlfs
$ sudo mount -a    
$ mount|grep puffs 
/dev/puffs on /sysctl type puffs|sysctlfs
/dev/puffs on /sysctl type puffs|sysctlfs
$ sudo mount -a    
$ mount|grep puffs 
/dev/puffs on /sysctl type puffs|sysctlfs
/dev/puffs on /sysctl type puffs|sysctlfs
/dev/puffs on /sysctl type puffs|sysctlfs
$ sudo mount -a    
$ mount|grep puffs 
/dev/puffs on /sysctl type puffs|sysctlfs
/dev/puffs on /sysctl type puffs|sysctlfs
/dev/puffs on /sysctl type puffs|sysctlfs
/dev/puffs on /sysctl type puffs|sysctlfs
$

	The same happens with ntfs-3g, so perhaps is a general problem
	in PUFFS.

>How-To-Repeat:
>Fix:
	Yes, please.
