Follow-up Comment #2, bug #48265 (project grub):
In my opinion, we could do the trick only with partuuid support on
grub-probe.
Partuuid changes, its bad idea set on stone. Much better work with fs labels.
1) get partition grub spec with grub-search
2) get partuuid with patched grub-probe
Defining this function,
function label2partuuid{
LABEL=$1
search --no-floppy --label --set=GRUBPART $LABEL
probe --fs-partuuid --set PTUUID $GRUBPART
}
Changing kernel line,
root=PARTUUID=$PTUUID
Great news for ramdiskless systems if done.
Does your patched probe allow this?
