You need to change that. Based on: mr-nosey ~ # ls -la /dev/mapper/vg-root brw------- 1 root root 254, 0 Aug 19 06:04 /dev/mapper/vg-root The line in build-initrd.sh read (high levels of guessing going on here): mknod dev/root b 254 0 I don't know about this. That lvm2create_initrd script says, "# Device-Mapper dynamically allocates all device numbers. " > Also, step 4c (at line 564) needs to be changed to run "/lib/lvm > vgscan".

The error returned by the patched script, after entering the password for losetup, was: "Failed to create LVM2 system dir for metadata backups, config files and internal cache. Set environment variable LVM_SYSTEM_DIR to alternative location or empty string." This appears to be consistent with a line in http://sources.redhat.com/cgi-bin/cvsweb.cgi/~checkout~/LVM2/scripts/lvm2create_initrd/lvm2create_initrd?content-type=text/plain&cvsroot=lvm2&only_with_tag=HEAD "echo "$PRE Remounting / read/write" mount -t ext2 -o remount,rw /dev/ram0 /" Jari, I think you're getting closer. I can almost smell that booting logical volume. Regards Fog_Watch. -- Lose wait. Get Gentoo. - Linux-crypto: cryptography in and on the Linux system Archive: http://mail.nl.linux.org/linux-crypto/
