Add a python script which implements the bulk of this functionality. Over time, this would ideally evolve into a library of python routines which can be used to inspect kernel data structures and automate some debugging tasks, similar to jhb's out-of-tree scripts, but written in a somewhat nicer language and with better integration into the kgdb command prompt. Note that kgdb currently won't auto-load scripts in this directory. This should perhaps change in the future. It probably also makes more sense to have a crashinfo.py which provides all the kgdb output that we want to include in core.txt, rather than having crashinfo.sh pipe in several commands.

Note: If you modify these files, please keep hier(7) updated!
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/ *$//' >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 committed, as it 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.
