# bsd.destdir.mk - Support for chrooted installation

#
# The target order is always: pre-chroot do-chroot post-chroot
#
# pre-chroot
# - You can use this for special preparation work, that
# want to do before chrooting into the destination
# environment and doing the real build. At default
# this target is empty.
#
# do-chroot
# - This is the main target for doing the chrooted
# operations. It mounts the ports tree and devfs into
# the destination environment and starts make(1)
# by calling chroot(1).
#
# post-chroot
# - This target runs chrooted just after chroot(1) was
# called. You can use this for special preparation
# work for the chrooted build if necessary. At
# default, this target is empty.
#
# DESTDIR_ENV_LIST
# - Contains names of the variables in host environ(7),
# which should be imported into the chrooted environ
# along with their values.
# Default: empty.
#
# DESTDIR_MOUNT_LIST
# - Contains the directories to mount into the
# destination. This is to make PORTSDIR, DISTDIR, etc.
# available in the destination environment. Three
# forms of entries are allowed:
# VAR
# - Mounts the path contained by VAR into
# a temporary directory and sets VAR to that
# directory in the destination environ(7).
# VAR:HOST_PATH
# - Mounts HOST_PATH to a a temporary directory
# and sets VAR to that directory in the
# destination environ(7).
# VAR:HOST_PATH:DEST_PATH
# - Mounts HOST_PATH to DEST_PATH and sets VAR
# to DEST_PATH in the destination environ(7).
# Default: PORTSDIR DISTDIR
#
# You can use something like this in host /etc/make.conf to
# customize per-chroot environment:
# .if ${DESTDIR}=/foo/bar
# PREFIX=/opt
# CFLAGS=-O3 -pipe
# DESTDIR_ENV_LIST=PREFIX CFLAGS
# .endif
