Two more things to note
1.) I just opened bug 672986 that euca-bundle-vol should copy uuid
2.) above, I stated that grub2 loads the kernel on uec and pv-grub. It may
have similar issues.
** Description changed:
- Binary package hint: cloud-init
+ Binary package hint: grub-legacy-ec2
I booted a maverick instance, modified it a bit, and created a snapshot
of that volume.
I then, booted another maverick instance like:
run-instances ami-548c783d --instance-type t1.micro --block-device-mapping
/dev/sdh=${SNAPSHOT}:${SIZE}
the surprising result was that the instance booted with root = /dev/sdh.
The reason for that is that menu.lst in the instance says:
kernel /boot/vmlinuz-2.6.35-22-virtual root=LABEL=uec-rootfs ro
console=hvc0
initrd /boot/initrd.img-2.6.35-22-virtual
In this instance, there were, then 2 filesystems that had LABEL=uec-rootfs.
The kernel just chose /dev/sdh.
update-grub-legacy-ec2 is what writes the 'LABEL=uec-rootfs'.
