I thought that labels, ids, etc, did not work on grub. There is a map

we see usb devices, here (and I have none connected, have to be
internal usb-hubs) but for me HDD is still 0

AIUI:

1-device.map is used by the grub shell
2-grub _shell_ is not part of normal boot process

Maybe I have something about this mixed up and it is Bob S's 11.2 device
map that needs fixing.

Does Grub v1 actually know how to use /dev/disk* entries? I don't remember
ever seeing device.map files of more than 45 or so bytes on any of my 11.2
or Factory installs, too small to be using /dev/disk* strings for mapping.

Do mkinitrd or perl-Bootloader depend on correct device.map entries to
function correctly?

Bob, show us your 11.2 device.map file please.

OK, here it is, exactly the same as 11.0

(hd0) /dev/sda
(hd1) /dev/sdb
(hd2) /dev/sdc
