# Makefile snippet to add ${MAKEDEVTARGETS} devices to the mtree list
# (if set), otherwise copy etc.${MACHINE}/MAKEDEV to ./dev
#
#
# Required variables:
# _SRC_TOP_ top level of src tree (set by <bsd.own.mk>)
# MACHINE machine name (set externally by build framework)
#
# Optional variables:
# MAKEDEVTARGETS targets to create with etc/etc.${MACHINE}/MAKEDEV
#
# Variables modified by this:
# MTREECONF may get "devices.spec" added to it
#

# used to build the file system
