If so, sorry for the > noise, as I'd never seen that type of usage, and certainly would not miss it. Oh.. the name, say, root=/dev/sda999 should work (well, that's the plan) but as there will be no fixed mapping between /dev/sdaN and MAJ:MIN when N > 15, root=MAJ:MIN just isn't possible for dynamically allocated ones. I hope it clarified things a bit. Thanks. -- tejun
