Subject: [PATCH] HAL: Ignore internal DM devices with new DM udev rules From: Milan Broz Date: Tue, 13 Jul 2010 14:08:14 +0200 With new device-mapper udev rules are /dev/mapper/* symlinks to basic device name /dev/dm-X. (Change requested by udev upstream.) This change breaks temporary-cryptsetup workaround inside hal. With new dm-udev rules (uncluded since device-mapper 1.02.39) there is DM_UDEV_DISABLE_OTHER_RULES_FLAG variable which controls that scan should be ignored for this device (it is set for all internal devices, including temporary cryptsetup, internal parts of lvm devices etc.) Ignore device if this flag is set.
