Subject: dmsetup: udev rules breaks normal devices permissions (i.e /dev/null)

Date: Wed, 16 Jul 2008 20:39:51 +0200

Package: dmsetup
Version: 2:1.02.27-1
Severity: critical
Justification: breaks unrelated software

Hi,

Version 2:1.02.27-2 introduces /etc/udev/rules.d/65_dmsetup.rules.
These rules break the normal behaviour of udev.

I remarked most of the devices have no more their permissions updated. i.e.
/dev/null, /dev/random, /dev/zero, ... which has 660 instead of 666. This
prevent some software to start (i.e fecthmail).
I tried to rebuild the initramfs (update-initramfs -k all -u) which renders the
system unbootable.
I've reverted to 1.02.27-1 which didnt fix the problem by itself. A diff from a
backup shows me that the udev rules was added. I've deleted it and rebuilt the
intitramfs which fixed the problem.

My system is built on lvm2 over raid1 (boot partition is not on lvm).

Regards

Jean-Luc

/etc/udev/rules.d/65_dmsetup.rules needs to be changed so that the three 
first lines all have GOTO="device_mapper_end".

Confirmed that this resolves the problem.
