When I run "update-grub", the file "grub.cfg" will contain lines like this.

menuentry 'Ubuntu...' {
    ...
    linux /boot/vmlinuz... root=/dev/md124 ...
    ...
}

For the line of linux, is it possible to let it use UUID? Like,

    linux /boot/vmlinux... root=UUID=xxx

Right now, every time after I do update-grub, I have to manually edit the line to use UUID. Otherwise, the boot will fail.

Thanks for the help.

I just updated from 11.10 to 12.04, with no major problems (it took a while to get past a request to restart ssh, mysql and some other services, but I did no fiddling by myself, everything was done by the installer). However, after restarting, grub can't do anything. Picking the new linux installation… >>> More
