yesterday I changed the name of my ROOT-partition, a logical volume, as I had omitted the last "t" in its name from von 'LV-ROO' to 'LV-ROOT', but didn't think of updating GRUB. Now GRUB refuses to mount my ROOT-partition, as it can't find one with the old name.
How best to proceed? It won't suffice just to manually change the entry in /boot/grub.cfg via a live system I suppose. This is GRUB2, so if I remember correctly, it works by calling 'external' scripts to build its grub.cfg
. Adjusting the initramfs will probably also be needed.
My system (Sabayon Linux) is set up as follows
ROOT-Partition (Logical Volume)
SWAP-Partition (Logical Volume)
HOME-Partition (Logical Volume)
Thanks a lot for your kind help, I'm sure this can be fixed.
