udev.rules: /dev/dm-* devices, possible side effects

[Michael Biebl]

Hi,

/etc/udev/udev.rules at line 99ff contains the following:

# device mapper creates its own device nodes, so ignore these
KERNEL=="dm-[0-9]*",           NAME=""

This prevents /dev/dm-* device nodes from being created for e.g. luks
encrypted partitions.

As I intend to package gnome-mount, which relies on /dev/dm-* devices
for properly dealing with luks encrypted partitions, I asked David
Zeuthen (author of gnome-mount) and Kay Sievers (co-author of udev).
They told me, that the above udev rule should be removed.
As Marco d'Itri (CC, Debian maintainer of udev) wanted to avoid any
breakage in lvm/dm related packages, and he couldn't remember anymore
why he had added this rule some time ago, he told me, to ask you first,
if removing the above line above again is safe or if it would
potentially break dm related packages.


Cheers,
Michael
