I got the same error on a clean installation of sarge using the debian default kernel 2.6.8-2-386.
I can use "cryptsetup create" without any problems on a shell, but inside an initrd.img it fails with the "Incompatible libdevmapper" message. -- kiu -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
