1Note: If you modify these files, please keep hier(7) updated! 2 3These files are used to create empty file hierarchies for building the 4system into. Some notes about working with them are placed here to try 5and keep them in good working order. 6 7 a) The files use 4 space indentation, and other than in the header 8 comments, should not contain any tabs. An indentation of 4 is 9 preferable to the standard indentation of 8 because the indentation 10 of levels in these files can become quite deep causing the line to 11 overflow 80 characters. 12 13 This also matches with the files generated when using the 14 mtree -c option, which was implemented that way for the same reason. 15 16 b) Only directories should be listed here. 17 18 c) The listing should be kept in filename sorted order. 19 20 d) Sanity checking changes to these files can be done by following 21 this procedure (the sed -e is ugly, but fixing mtree -c to 22 not emit the trailing white space would be even uglier): 23 24 mkdir /tmp/MTREE 25 mtree -deU -f BSD.X.dist -p /tmp/MTREE 26 mtree -bcdjn -F freebsd9 -k uname,gname,mode -p /tmp/MTREE | \ 27 sed -e 's/ *$//' >BSD.X.new 28 diff -u BSD.X.dist BSD.X.new 29 rm -r /tmp/MTREE 30 31 Note that you will get some differences about /set lines, 32 and uname= gname= on certain directory areas, mainly man page 33 sections. This is caused by mtree not having a look ahead 34 mechanism for making better selections for these as it 35 traverses the hierarchy. 36 37 The BSD.X.new file should NOT be committed, as it will be missing 38 the correct header, and important keywords like ``nochange''. 39 Simply use the diff for a sanity check to make sure things are in 40 the correct order and correctly indented. 41 42 e) Further sanity checking of the system builds with DESTDIR=/someplace 43 are more complicated, but can often catch missing entries in these 44 files. I tend to run this more complete sanity check shortly after 45 the target date for a new release is announced. 46 47 If you want details on it bug me about it via email to 48 rgrimes@FreeBSD.org. 49
