From mboxrd@z Thu Jan 1 00:00:00 1970 From: Benjamin Gilbert Date: Thu, 21 May 2009 20:31:33 +0000 Subject: Newer udev not performing %-substitutions on OWNER and GROUP Message-Id: <4A15BA25.7030100@cs.cmu.edu> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: linux-hotplug@vger.kernel.org I have a udev rule that sets the ownership of a device node based on the result of a PROGRAM run, e.g.: ..., PROGRAM="echo 1000", OWNER="%c" This works in Fedora 10 (udev-127) and Ubuntu 8.10 (udev-124) but not in Fedora Rawhide (udev-141) or Ubuntu 9.04 (udev-141). Further investigation reveals that on the affected systems, substitutions appear not to be working at all for OWNER and GROUP keys. (I tried %c, %m, %M, %n, and $result.) Replacing OWNER="%c" with OWNER="1000" works for me, as does SYMLINK+="%c", so the rule is being properly executed. Is this syntax still supported for OWNER and GROUP? udev(7) claims that it is. --Benjamin Gilbert
