lucid: update-grub does not work with 4 character disk names in /dev

[Jochen Barth]

We're using Lucid 10.04.3 (Server, 64 Bit) and have a lot of attached disks.
During installation, there has been only one drive named /dev/sda, everything worked fine.
Now we've attached all storage, update-grub (which calls grub-probe) does not work anymore:

root@xxx:/root# grub-probe -v -t fs_uuid -d /dev/sdby
grub-probe: info: »/boot/grub/device.map« kann nicht geöffnet werden.
grub-probe: info: /dev/sdby starts from 0.
grub-probe: info: opening /dev/sdb.
grub-probe: info: the size of /dev/sdb is 4194304000.
grub-probe: error: unknown filesystem.

Have a look at the /dev - names: in the third output line grub-probe is talking about "sdb" instead of "sdby".

We made an inconvenient (not easily transferable) workaround using udev:
root@...:# cat /ect/udev/rules.d/61-persistent-local-drive.rules
KERNEL=="sd*", ENV{DEVTYPE}=="disk", ENV{ID_SERIAL}=="3600508e000000000f92b957d13e3870a", NAME="sda"
KERNEL=="sd*", ENV{DEVTYPE}=="partition", ENV{ID_SERIAL}=="3600508e000000000f92b957d13e3870a", NAME="sda%n"

Version of grub-pc is 1.98-1ubuntu5

I think, this is the same bug as

Isn't there any solution?

The described workaround seems not to work in every case.
