It mostly succeedes, but I was unable to boot the new system. When I boot, it fails as follows: >> Activating mdev >> Determining root device !! Block device /dev/mapper/lovesong-gentoo is not a valid block device !! The root block device is unspecified or not detected Please specify a device to boot, or "shell" for a shell boot() :: Now I originally installed this system using a chroot from a Debian etch system. I used genkernel to generate the kernel. As far as I can remember, I did specified the --lvm option. Now perhaps the kernel is not OK because I ran genkernel in a chroot running on a Debian kernel... Perhaps I chose the wront options... Perhaps I can fix things by rerunning genkernel with different options... Or perhaps I need to start all over from a full-fledged gentoo install CD. Please advise. -- hendrik P.S.
