# generate mtree style manifest supported by makefs in FreeBSD
|
|
|
|
# input looks like
|
|
# MANIFEST= my.mtree
|
|
# for each MANIFEST we have a list of dirs
|
|
# ${MANIFEST}.DIRS += bin sbin usr/bin ...
|
|
# for each dir we have a ${MANIFEST}.SRCS.$dir
|
|
# that provides the absolute path to the contents
|
|
# ${MANIFEST}.SRCS.bin += ${OBJTOP}/bin/sh/sh
|
|
# ${MANIFEST}.SYMLINKS is a list of src target pairs
|
|
# for each file/dir there are a number of attributes
|
|
# UID GID MODE FLAGS
|
|
# which can be set per dir, per file or we use defaults
|
|
# eg.
|
|
# MODE.sbin = 550
|
|
# MODE.usr/sbin = 550
|
|
# MODE.dirs = 555
|
|
# means that sbin and usr/sbin get 550 all other dirs get 555
|
|
# MODE.usr/bin/passwd = 4555
|
|
# MODE.usr/bin.files = 555
|
|
# MODE.usr/sbin.files = 500
|
|
# means passwd gets 4555 other files in usr/bin get 555 and
|
|
# files in usr/sbin get 500
|
|
# STORE defaults to basename of src and target directory
|
|
# but we can use
|
|
# ${MANIFEST}.SRCS.sbin += ${OBJTOP}/bin/sh-static/sh-static
|
|
# STORE.sbin/sh-static = sbin/sh
|
|
#
|
|
# the above is a little overkill but means we can easily adapt to
|
|
# different formats
