Some notes about working with them are placed here to try +and keep them in good working order. + + a) The files use 4 space indentation, and other than in the header + comments, should not contain any tabs. An indentation of 4 is + preferable to the standard indentation of 8 because the indentation + of levels in these files can become quite deep causing the line to + overflow 80 characters. + + This also matches with the files generated when using the + mtree -c option, which was implemented that way for the same reason. + + b) Only directories should be listed here. + + c) The listing should be keep in filename sorted order. + + d) Sanity checking changes to these files can be done by following + this procedure (the sed -e's are ugly, but fixing mtree -c to + not emit the trailing white space would be even uglier): + + mkdir /tmp/MTREE + mtree -deU -f BSD.X.dist -p /tmp/MTREE + mtree -cdin -k uname,gname,mode | sed -e 's/ *$//' | \ + sed -e 's/^#\t//' >BSD.X.new + diff -u BSD.X.dist BSD.X.new + rm -r /tmp/MTREE + + Note that you will get some differences about /set lines, + and uname= gname= on certain directory areas, mainly man page + sections. This is caused by mtree not having a look ahead + mechanism for making better selections for these as it + traverses the hierarchy. + + The BSD.X.new file should NOT be commited, will be missing the + correct header, and important keywords like ``nochange''. Simply + use the diff for a sanity check to make sure things are in the + correct order and correctly indented. + + e) Further sanity checking of the system builds with DESTDIR=/someplace + are more complicated, but can often catch missing entries in these + files. I tend to run this more complete sanity check shortly after + the target date for a new release is announced. + + If you want details on it bug me about it via email to + rgrimes@FreeBSD.org. |
