>Description:
BSD/OS has this cool feature where it says things like "Configuration
changed:" followed by diffs showing any changes in dmesg output. This
can be very handy when debugging.
At the same time, there's also a /var/db/dmesg.boot showing what the
system's boot-time configuration was like.
>How-To-Repeat:
Boot a system. :)
>Fix:
Save this script as /sbin/chkconfig. In /etc/rc, right near the end, add:
---
echo "Checking system configuration..."
chkconfig
---
I put it before the 'date' at the end.
This script is structurally fairly similar to the BSD/OS chkconfig, and in
particular, that's where I got the idea for the sed script.
The chkconfig man page is pretty trivial, but could be written if there's
any interest.
#!/bin/sh
umask 022
old=/var/db/dmesg.boot
new=/tmp/ck$$.dmesg
out=/tmp/ck$$.out
dmesg | sed -n -e '/^NetBSD/ { x ; n ; }' -e 'H' -e '$ { x ; p ; }' > $new
if [ ! -f $old ]
then echo >&2 "No old configuration to compare with."
cp $new $old
exit 1
fi
diff $old $new > $out
if [ -s $out ]
then echo >&2 "Configuration changed:"
cat $out
R=1
else R=0
fi
cp $new $old
rm -f $new $out
exit $R
