Subject: sysv-rc: update-rc.d option to redo all symlinks for all pacakges to their postinst defaults

Date: Wed, 16 Nov 2005 15:36:45 +0200

Package: sysv-rc
Version: 2.86.ds1-5
Severity: wishlist

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

It would be desirable to have an option to redo all symlinks for all packages (if no package name is passed as 
argument; otherwise only redo the package passed as argument), to be used manually to clean up after upgrading to 
more recent versions of certain packages that leave no longer needed symlinks.

Subject: Bug#339460: update-rc.d: a partial implementation of what I propose

Date: Wed, 16 Nov 2005 15:55:11 +0200

[Message part 1 (text/plain, inline)]

1) find out which packages have bootup scripts:
"dpkg -S /etc/init.d/* | cut -f 1 -d : | uniq | sort | uniq"
Caveat:  find a way to remove scripts that belong to no package.

2) for-next loop removing all symlinks for each, using update-rc.d

3) for-next loop redoing the post-install scripts of each (which is
where update-rc.d would make the symlinks during installation).

Ugly but it does a fine job as a proof of concept:

#!/bin/sh
# restore RC symbolic links per each package's postinst script defaults
packages=`dpkg -S /etc/init.d/* | cut -f 1 -d : | sort | uniq | xargs`
for name in $packages; do
        update-rc.d -f $name remove
done
apt-get --reinstall install $packages
#EOF

Of course, ideally, we would have all package scripts guaranteed to be
fully idempotent, which would then make it easier to just grep and call
each /var/lib/dpkg/info/$name.postinst for a replay.

Implementing this requires implementing some mechanism whereby the factory
default configuration is recorded somewhere.  The latter has been requested
before so I am merging this report.
