Hi, all.

# uname -a
NetBSD xenu 3.99.13 NetBSD 3.99.13 (DSM_XENU) #1: Wed Dec 7 16:59:56 JST 2005
h-masuda@dsmserv.dsm.cis.kit.ac.jp:/usr/current/src/sys/arch/i386/compile/DSM_XENU i386
# mount -t mfs -o -s=10240,-p=755 none /.var
# mount -t union /.var /var

 Using mfs is OK, but,

# mount -t tmpfs -o -m=755 none /.var
# mount -t union /.var /var
mount_union: /.var on /var: Operation not supported

 Any idea?
