# NOTE:
#
# * 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.
