I saw the need so I wrote the attached script.
Read the comments at the top of the script but basically the bourne
shell script "etcud"
(meaning /etc update) does a comparison between /usr/src/etc and /etc
with MD5
checksums. It will optionally show you RCS version id's, diffs between
files, and all
files (not only those where the MD5 checksums mismatch). One of the
best features
is the ability to specify an egrep exclusion or inclusion pattern for
file names. And there
is also option -t for typical usage which excludes common files which
are bound to
mismatch the MD5 checksum comparison.
I seriously think this script should be run by people after each make
world like:
"etcud -t -v".
Anyway, here is the usage:
Usage: etcud [-a] [-v] [-d] [-n] [-t] [-r <dir>] [-i <patt> | -e <patt>]
-a Also output information for files where the checksums
match
-v Display RCS version strings if present
-d Display diffs between the files
-n Non-exact mode - i.e. dont use '-x' with egrep
-t Typical usage. This is the same as etcud -e
"group|hosts|motd|shells|rc.local|master.passwd"
-r <dir> Directory where the source distribution is found
-i <patt> Inclusion filename pattern (those files to check)
-e <patt> Exclusion filename pattern (those file to ignore)
And here is some sample output for my -CURRENT upgrade from
ctm-src-cur.2947
to ctm-src-cur.3002:

"If it is true that our Universe has a zero net value for all conserved
quantities, then it may simply be a fluctuation of the vacuum of some
larger space in which our Universe is imbedded. In answer to the
question of why it happened, I offer the modest proposal that our
Universe is simply one of those things which happen from time to time."
E. P. Tryon from "Nature" Vol.246 Dec.14, 1973

# etcud 1.3 - Compare /etc with /usr/src/etc to check for updated files
#
# etcud [-a] [-v] [-d] [-n] [-t] [-r <directory>] [-i <pattern> | -e <pattern>]
#
# This script compares the MD5 checksums of files found in the etc
# directory of the source distribution (/usr/src/etc by default) with
# those in /etc to alert you when /etc files need updating.
#
# Options:
#
# -a Also output information for files where the checksums match.
# -v Display RCS version strings if present.
# -d Display diffs between the files.
# -n Non-exact mode. i.e. dont use '-x' with egrep for inclusion
# and exclusion patterns. For power users only!
# -t Typical usage. This is the same as etcud -e $DEF_EXCL
# -r <dir> Set the root directory of the source distribution.
# -i <patt> Inclusion filename pattern (those files to check).
# -e <patt> Exclusion filename pattern (those file to ignore).
#
# Inclusion and exclusion patterns must be an egrep pattern which is a list
# of file names separated by the pipe character. The filenames must be
# relative to the etc directory of the source distribution (/usr/src/etc
# by default).
#
# By default the script will use egrep -x which means the patterns must
# exactly match for the files to be included or excluded. This is
# generally what you want as you probably want to be able to type
# "etcud -e hosts" to exclude the file /etc/hosts but not the file
# /etc/hosts.lpd. Power users can use -n to disable the use of -x
# with egrep. This can be useful when dealing with the ppp directory
# for example.
#
# NOTES
# - You can use EITHER an exclusion OR an inclusion file pattern, not
# both. Subsequent uses will be ignored with a warning.
#
# - Use of the typical option (-t) will run etcud with the default
# exclusion pattern, set at $DEF_EXCL below. This mode overrides
# any previously specified inclusion or exclusion patterns with a
# warning. This mode also silently ignores -n.
