I have installed some Ubuntu on my LVM disks. In Ubuntu10.04, I rename the Ubuntu12.04's lv but the "linux-boot-probe" goes wrong.
Here is what I did:
sudo lvname LVMDisk Ubuntu12.04 LabUbuntu12.04 #I have installed Ubuntu12.04 on this lv
sudo linux-boot-prober /dev/mapper/LVMDisk-LabUbuntu12.04
The following is the result. We still can see root=/dev/mapper/LVMDisk-Ubuntu12.04
.
It doesn't change? Why?
/dev/mapper/LVMDisk-LabUbuntu12.04:/dev/mapper/LVMDisk-LabUbuntu12.04:Ubuntu, with Linux 3.2.0-30-generic-pae:/boot/vmlinuz-3.2.0-30-generic-pae:/boot/initrd.img-3.2.0-30-generic-pae:root=/dev/mapper/LVMDisk-Ubuntu12.04 ro quiet splash $vt_handoff
