Hello list,

Hardly had I said that MBR had caused me no problems in years, guess what? It 
did. I tried to mount /boot (ext2) to install a new kernel but it couldn't be 
mounted - wrong fs type or some such. When I got it mounted as ext4 it looked 
fine. Fsck had found nothing wrong either, but fdisk showed the wrong partition 
as Active. /boot is on /dev/md1 which is RAID-1 built on /dev/sd[ab]1, so sda1 
should have been marked Active (it was when I set it up), but the spare, empty 
sda2 was instead.

On booting a rescue system and correcting the Active flag with fdisk, all the 
files in it disappeared. So I put them back in and booted the main system. Same 
all over again.

In the end I just zapped /, /var, /usr/portage etc, restored from an older 
backup, synced and emerged -e world. Then restoring the files in /boot resulted 
in a stable system.

Looks like time I investigated GPT or BTRFS. But I don't want to go from GRUB 
legacy to GRUB-2. Is that possible?
