[gentoo-user] root fs moved, but no init

[Adam Carter]

Summary;
Copied / from sda3 to sdb3
Updated the fstab in the new disk (/dev/sdb3       /
btrfs           noatime,compress=lzo    0 0)
Updated the kernel line's root=/dev/sda3 to /dev/sdb3 in grub.conf,
but left the root (hd0,0) as it is. So, kernel is loaded from sda but
init should run from sdb.
When booting the kernel successfully mounts /dev/sdb3 as root fs
Then the system halts at one of the freeing memory messages, but I
assume the problem is that init isn't executed from /dev/sdb3

Since root is mounted, i know i have all the drivers I need in the
kernel. Any ideas why booting stops?
