[Bug 1319047] [NEW] udev rule file naming requirements changed breaking compatibility to Ubuntu 12.04

[linuxball]

Public bug reported:

Binary package:

  udev:
    Installed: 204-5ubuntu20
    Candidate: 204-5ubuntu20
    Version table:
   *** 204-5ubuntu20 0
          500 http://de.archive.ubuntu.com/ubuntu/ trusty/main amd64 Packages
          100 /var/lib/dpkg/status

Source package:
  systemd 

Ubuntu release:
  Description:	Ubuntu 14.04 LTS
  Release:	14.04


Expected behavior:

  All rule files in /etc/udev/rules.d/ having the extension '.rules'
[see udev(7)] should be honored by udevd (as it has been in Ubuntu 12.04
and as it is still by "udevadm test <syspath>").

Actual behavior:

  If udev rule file has an additional '.' (dot) in its name (e.g.
"graphics-xorg.conf.rules) it will be silently ignored by udevd. But
such a file will not be ignored by "udevadm test <syspath>", which even
adds to the confusion about why the rule is not working. Also the man
page udev(7) does not mention any additional/new naming requirements.

How to reproduce:

  Create or rename a rule file in /etc/udev/rules.d/ so that its name
contains an additional '.' (dot) (beside the one in '.rules', e.g.
'graphics-xorg.conf.rules') and run "udevadm control --reload". From now
on the udev rules in that file will be ignored silently by udevd (but
not by 'udevadm test <syspath>'!).

How to solve this issue:

  (1) Revert to the old behavior and make udevd honor rule file names as in Ubuntu 12.04 (preferred alternative)
  __OR__
  (2) If this change has been introduced intentionally then 
     (2a) Announce it (e.g. in a changelog and/or upgrade guide so that users/admins know about it and can rename their rule files not matching the changed needs)
     (2b) Change the code of "udevadm test" (and possibly other tools) to behave consistently so that users have a chance to narrow down the naming issue
     (2c) Add the changed naming requirement to man page udev(7), info files, tutorials... 

Urgency/Importance:
  Normal
