These files are used to create empty file hierarchies for building the
|
|
system into. 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 kept in filename sorted order.
|
|
|
|
d) Sanity checking changes to these files can be done by following
|
|
this procedure (the sed -e is 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 -p /tmp/MTREE | \
|
|
sed -e 's/ *$//' | tail +5 >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.
