Bug#674218: makedev: please drop obsolete preinst script



Package: makedev
Version: 2.3.1-91.1
Severity: wishlist
Tags: patch
User: ubuntu-devel@lists.ubuntu.com
Usertags: origin-ubuntu quantal ubuntu-patch

Hi Bdale,

A bug was recently reported in Ubuntu about a debootstrap failure, that
ultimately turned out to be related to the recent change to makedev's
preinst now being set -e.

  https://bugs.launchpad.net/ubuntu/quantal/+source/makedev/+bug/1001460

To make a long story short, makedev's preinst was running commands which,
while they are meant to be totally safe, are unnecessary on any recent
Debian or Ubuntu system and turned out not to be safe in Ubuntu for the
specific case of debootstrapping.

Since nothing in this preinst is needed on on upgrades from any recent
release (one of the upgrade fix-ups only applies to upgrades from lenny -
oldstable - and the other only applies to upgrades from something pre-etch),
I would suggest dropping the preinst entirely as in the attached patch. 
It's unlikely that the specific bug that hit Ubuntu here will ever affect
Debian, but IMHO the fewer preinsts we have in the base system, the better.

Thanks for considering,
