16281760Ssjg# generate mtree style manifest supported by makefs in FreeBSD

18281760Ssjg# input looks like
19281760Ssjg# MANIFEST= my.mtree
20281760Ssjg# for each MANIFEST we have a list of dirs
21281760Ssjg# ${MANIFEST}.DIRS += bin sbin usr/bin ...
22281760Ssjg# for each dir we have a ${MANIFEST}.SRCS.$dir
23281760Ssjg# that provides the absolute path to the contents
24281760Ssjg# ${MANIFEST}.SRCS.bin += ${OBJTOP}/bin/sh/sh 
25281760Ssjg# ${MANIFEST}.SYMLINKS is a list of src target pairs
26281760Ssjg# for each file/dir there are a number of attributes
27281760Ssjg# UID GID MODE FLAGS
28281760Ssjg# which can be set per dir, per file or we use defaults
29281760Ssjg# eg.  
30281760Ssjg# MODE.sbin = 550
31281760Ssjg# MODE.usr/sbin = 550
32281760Ssjg# MODE.dirs = 555
33281760Ssjg# means that sbin and usr/sbin get 550 all other dirs get 555
34281760Ssjg# MODE.usr/bin/passwd = 4555
35281760Ssjg# MODE.usr/bin.files = 555
36281760Ssjg# MODE.usr/sbin.files = 500
37281760Ssjg# means passwd gets 4555 other files in usr/bin get 555 and
38281760Ssjg# files in usr/sbin get 500
39281760Ssjg# STORE defaults to basename of src and target directory
40281760Ssjg# but we can use 
41281760Ssjg# ${MANIFEST}.SRCS.sbin += ${OBJTOP}/bin/sh-static/sh-static
42281760Ssjg# STORE.sbin/sh-static = sbin/sh
43281760Ssjg#
44281760Ssjg# the above is a little overkill but means we can easily adapt to
45281760Ssjg# different formats
