FYI all, I figured out the problem, it was my mistake, because the initramfs was actually OK, but I had too boot partitions (one for the original system, one for the backup), and I was updating the wrong one (and booting from the other...) Once I figured out, it did work -- now I have another issue. Tc -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
