There is no reason to keep a diversion if the package creating it is no longer
there; in fact, this is harmful. These should be cleaned up automatically.

thanks

Wichert.

Wichert,

I know left-over diverts are not dpkg's fault, but please consider detecting
left-over diverts on --purge (and maybe just removal), and complaining
loudly in the console with a big WARNING.

I've had diverts causing minor security hazards here, because a package
left-over diverts caused another to never ever update its config files. This
divert was nearly an year old, so I was quite distraught by the huge
opportunity window it left in my system :(

  This sounds more like a feature request for dpkg than for apt.  (it
also sounds like a bug in nvidia-glx to me, but registering which package
a given diversion belongs to also seems like a good idea to me)

  Ccing this to bug #45480 since it seems to be relevant.

Subject: Feature request: 'dpkg-divert --rename --remove' with Aptitude
To: dburrows@debian.org

Hi!

I have a little feature request (or see it as a bugfix ;-)) for Aptitude. I
resently installed Etch and realised that Aptitude does a great job renaming
files with help of dpkg-divert but hten you purge that package Aptitude
doesn't remove that diverted name. So then you are going to install a new
package with such file you get an error message like this (in Swedish, but
I'm sure you totaly understand that it says:

(Läser databasen ... 56282 filer och kataloger installerade.)
Packar upp nvidia-glx (från .../nvidia-glx_1.0.8762-2_i386.deb) ...
dpkg-divert: `diversion of /usr/lib/xorg/modules/extensions/libGLcore.a
to /usr/lib/nvidia/libGLcore.a.xlibmesa by nvidia-glx' clashes with
`diversion of /usr/lib/xorg/modules/extensions/libGLcore.a
to /usr/lib/nvidia/libGLcore.a.xlibmesa by nvidia-glx-legacy'

Today I learned to use:
# dpkg-divert --rename --remove /usr/bin/example.foo
but I should recomend you to built in this function in Aptitude so it remove
the deverted names on files that being removed or purged.

Best wishes
