mount(8) and the various mount_xxx programs like mount_mfs(8).

# uname -r
10.1
# pwd
/tmp/foo/bar
# mkdir baz && mount_mfs -s 8192 swap baz
mount_mfs: "baz" is a relative path.
mount_mfs: using "/tmp/foo/bar/baz" instead.
# df baz

mfs:14404            3791            0         3601   0% /tmp/foo/bar/baz
# umount baz
# rmdir baz
# mkdir baz && mount -t mfs -o -s=8192 swap baz
# df baz

# pgrep mount_mfs

I had aligned something in that area for netbsd-10, but IIRC mount_mfs
behaved as expected earlier.
