patch to update-rc.d

[Rajesh Deo <rajeshdeo@earthlink.net>]

Hi Everyone,

This is my first post to debian-devel. A fairly long message, hope it
will be tolerated.

I am currently developing a perl script that lists rc?.d
configuration and you can find it here:

http://www.chara.gsu.edu/~deo/sources/list-rc.d
http://www.chara.gsu.edu/~deo/sources/README

README shows the typical usage and expected output. Also available
is a patch to update-rc.d that includes the functions from the script.

http://www.chara.gsu.edu/~deo/sources/update-rc.d.list.patch

This enhances update-rc.d.pl to have a rc configuration listing
functionality. It is however _not_ emulating Red Hat's chkconfig and is
based on suggestions given in this discussion:

http://lists.debian.org/debian-devel/2001/12/msg00743.html

It also lists active services in /etc/inetd.conf and
/etc/xinetd.conf and /etc/xinetd.d. Apart from that it has a option that
will sort a given rc?.d to present the complete execution order within
that runlevel.

The script and the patch is in Perl (since update-rc.d is written in
Perl). I would appreciate any help in improving it. I had sent the first
version of list-rc.d to Miquel but I guess it got lost in his mailbox.

Any suggestions, comments and future directions are welcome. I am not a
official debian developer but would love to become one in future, with
appropriate guidance.

Happy holidays and season's greeting to everyone,
Rajesh Deo.
