# * MAKEDEV is used both as a standalone script (via "sh ./MAKEDEV
# all" or similar), and as a function library for MAKEDEV.local (via
# "MAKEDEV_AS_LIBRARY=1 . MAKEDEV"). Because of this, the script
# should consist almost entirely of function definitions, apart from a
# few lines right at the end.
#
# * MAKEDEV may be executed in an environment that is missing some
# common commands. For example, it may be executed from a minimal
# system used during installation, or it may be executed early in the
# boot sequence before most file systems have been mounted. It may
# also be executed in a cross-build environment on a non-NetBSD host.

Usage: ${0##*/} [-fMsu] [-m mknod] [-p pax] [-t mtree] special [...]
Create listed special devices. Options:
-f Force permissions to be updated on existing devices.
-M Create memory file system.
-m mknod Name of mknod(8) program. [\$TOOL_MKNOD or mknod]
-p pax Name of pax(1) program. [\$TOOL_PAX or pax]
-s Generate mtree(8) specfile instead of creating devices.
-t mtree Name of mtree(8) program. [\$TOOL_MTREE or mtree]
-u Don't re-create devices that already exist.
