# $OpenBSD: Makefile,v 1.4 2017/04/12 14:46:31 bluhm Exp $
# This regress test uses a disk template to create 15 partitions on
# a vnd device. All are initialized with a ffs file system. Then
# they are mounted nestedly in /mnt, see disktemplate for the tree
# layout. The unmount-nested test uses umount -f to unmount /mnt,
# without -f it does not work. It is checked that the kernel does
# the unmount recursively. There must be no dangling mount points.
# The whole tests have to be run as root.
