hotplug fails on postrm with purge:

The directories mentioned by rmdir does not exist. udev was never
installed on this machine (sarge).

Removing the offending rmdir in /var/lib/dpkg/info/hotplug.postrm makes
the package uninstall and purge cleanly.

Subject: rmdir not needed

The postrm includes:

       rmdir --ignore-fail-on-non-empty /etc/hotplug/.run/ /etc/hotplug/

These directories are included in the package and therefore should not
be removed in the postrm; dpkg will take care of them.

While we are on the subject ...

I would actually prefer it if /etc/hotplug/.run/ were not included in
the package but were handled the way ifupdown handles /etc/network/run/.
This entails deleting it in the postrm and creating it in the postinst
if it is not already a directory or symlink; and creating the target of
the symlink both in the postinst and in the initscript prior to the
point in time at which the directory is used.

/etc/default/hotplug and /etc/hotplug/.run/net.enable are deleted in
postrm too, so dpkg cannot unlink the directories because when it tries
to do it they are not empty.

Why?

dpkg removes the directories after the postrm runs.

So that /etc/hotplug/.run can be a symlink to /dev/shm/hotplug .

People on #debian-devel disagree too.

Please send a patch (which should also move /etc/hotplug/.run/ to
/dev/shm/).

I don't mind preparing a patch.  Note that /dev/shm/ can't be used on
devfs systems, which is one reason why we have been making the location
of run directories configurable by means of symlinks.

Subject: But woody's dpkg _was_ broken in this respect

Date: Sat, 12 Mar 2005 18:45:07 +0100

I think that directory removal by dpkg may have been broken in woody
(whose dpkg was version 1.9.21); perhaps that has to be taken into
account.

dpkg (1.10.11) unstable; urgency=low

Yes, this explains it. I will remove the rmdirs from all of my packages
post-sarge.

Subject: Fixed?

Date: Wed, 16 Mar 2005 08:55:42 GMT

I believe that this was fixed in 0.0.20040329-18:

Changes: 
 hotplug (0.0.20040329-18) unstable; urgency=high
 .
   * workaound fix to load firmware problem for sarge release.
     closes: Bug#297481, Bug#299154
     /sbin/hotplug may have potential problem in hotplug event multiplexing,
     but /sbin/udevsend has grave problem in firmware loading in old kernel,
     so I add workaround fix to this.
     Recommends upgrade kernel 2.6.10 or later.
   * fix purge problem in
hotplug.postrm.

It sure is. I just tried purging - I got a warning about
/etc/hotplug/.run did not exist, but the uninstall proceeded just
fine.
