4Note: If you modify these files, please keep hier(7) updated!
6These files are used to create empty file hierarchies for building the
7system into. Some notes about working with them are placed here to try
8and keep them in good working order.
10 a) The files use 4 space indentation, and other than in the header
11 comments, should not contain any tabs. An indentation of 4 is
12 preferable to the standard indentation of 8 because the indentation
13 of levels in these files can become quite deep causing the line to
14 overflow 80 characters.
16 This also matches with the files generated when using the
17 mtree -c option, which was implemented that way for the same reason.
19 b) Only directories should be listed here.
21 c) The listing should be kept in filename sorted order.
23 d) Sanity checking changes to these files can be done by following
24 this procedure (the sed -e is ugly, but fixing mtree -c to
25 not emit the trailing white space would be even uglier):
27 mkdir /tmp/MTREE
28 mtree -deU -f BSD.X.dist -p /tmp/MTREE
29 mtree -cdin -k uname,gname,mode -p /tmp/MTREE | \
30 sed -e 's/ *$//' | tail +5 >
31 diff -u BSD.X.dist
32 rm -r /tmp/MTREE
34 Note that you will get some differences about /set lines,
35 and uname= gname= on certain directory areas, mainly man page
36 sections. This is caused by mtree not having a look ahead
37 mechanism for making better selections for these as it
38 traverses the hierarchy.
40 The file should NOT be commited, will be missing the
41 correct header, and important keywords like ``nochange''. Simply
42 use the diff for a sanity check to make sure things are in the
43 correct order and correctly indented.
45 e) Further sanity checking of the system builds with DESTDIR=/someplace
46 are more complicated, but can often catch missing entries in these
47 files. I tend to run this more complete sanity check shortly after
48 the target date for a new release is announced.
