System: NetBSD weed.internal.vpn 1.6I NetBSD 1.6I (GENERIC) #0: Wed Oct 2 12:05:28 EST 2002 root@mofo:/data1/netbsd/current/20021002/i386/obj/sys/arch/i386/compile/GENERIC i386

>Description:
        mounted a memory file system of 256mb (1024 of free mem) and left it for about two days to come back to it to unmount it and umount is refuseing to see it, even tho mount shows it fine See Example:
	bash-2.05b# mount
	/dev/sd0a on / type ffs (local)
	/dev/sd0e on /usr type ffs (local)
	mfs:1388 on /usr/pkgsrc/www/squid/ type mfs (local)
	
	bash-2.05b# umount /usr/pkgsrc/www/squid/
	umount: /usr/pkgsrc/www/squid: not currently mounted

>How-To-Repeat:
        I took /usr/pkgsrc/www/squid/ and moved all of it's contents to a empty directory named ../backup then mounted /usr/pkgsrc/www/squid/ with a memory file system, copied all of it's contents back into the squid directory compiled squid and installed squid, walked away from it for about 2 days, came back to it, moved everything out of squid and back into backup and tryed to unmount it useing,./squid (from /usr/pkgsrc/www/) /usr/pkgsrc/www/squid/ as the unmount points, both giving me the same error, if i try to rm -rf squid i get a device busy error,this isn't a critical thing but i belive that it should be looked into before the 1.6.1 release.  If anyone has any questions about this feel free to email me.
BTW: This is a P4 2.0 ghz machine useing the i845G intel chipset, a gig of DDR 333 memory and a AHA-2940 scsi controller that is running a WD 36gb 10k rpm driveas it's hard drive.
