I have been using the dm-crypt interface to perform disk encryption. For example, I helped add dm-crypt/LUKS support to HAL[1]. Recently, I have found the cryptsetup no longer creates /dev/dm-X. Instead, the only device node created by the utility is /dev/mapper/Y (both were created previously.) I am using an up to date Fedora Core 6. I am trying to figure out what user-space tool/library was responsible for creating /dev/dm-X and why this device node is no longer created when I create a dm-crypt device. Could anyone point me in the right direction? The following bugs are related to this lack of /dev/dm-X device nodes because these programs rely on these nodes to determine a dm-crypt device's backing device: Red Hat Bug 216538: Lack of /dev/dm-? breaks hal's encrypted/LUKS volume support Red Hat Bug 124789: Add encrypted root filesystem support to mkinitrd [1] http://www.redhat.com/magazine/012oct05/features/hal/ -- Mike :wq -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
