[Pkg-dkms-maint] Bug#704150: dkms shouldn't rm old modules when you upgrade foo-dkms

[Jakub Turski]

Package: dkms
Version: 2.2.0.2-1~bpo60+1
Severity: normal


I'm using zfs-dkms and spl-dkms packages to automatically build zfs
modules for any new kernel. Thanks to combination of two bugs:

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=629245
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=635563

I was unable to build spl and zfs modules when relevant -dkms packages
got upgraded from 0.6.0.98 to 0.6.1. My recovery from this problem would
be much much easier, if dkms wouldn't simply *remove* old modules
(generated earlier from old version of {zfs,spl}-dksm packages), but
rather back them up somewhere.

Granted, ideally I should be able to pull the modules out from backup.
Given how big the compiled modules are, I think it'd be completely
reasonable if dkms kept a copy of them.
