I just tried dm-crypt and there appears to have been a change in the /dev interface. In 2.6.13 and linux-2.6.18 I'm seeing a /dev/device-mapper file. crw-rw---- 1 root root 10, 63 2006-09-12 21:33 /dev/device-mapper Note NOT a directory. The docs from Redhat device-mapper.0.96.03 thru device-mapper.1.02.09 all seem to say: /dev/mapper was called /dev/device-mapper prior to 0.96.04. Consequently scripts/devmap_mknod.sh has been updated. and seem to expect a DIRECTORY. Maybe this is a udev problem, but I suspect it's a device-mapper problem. Perhaps I need to go back before 0.96.03. I'll look into the new New LVM2/device-mapper development tarballs; my guess is it doesn't work with Linus kernel on kernel.org. -piet -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
