Bug#395019: More details regarding disk numbering change

[Paul TBBle Hampson]

For people (like me) who've picked up this bug via rc-alert or
apt-list-bugs and paniced..

The change is simply that partition numbers start at 1, not 0.
See [1]

As for the bug itself...

I'd suggest a NEWS.Debian file entry that says that grub2 users
must do an install-grub and update-grub cycle when upgrading to
this version, and make update-grub deal with the new numbering,
as well as telling users to update any static grub.cfg stanzas.

I guess the hard part is fixing the existing groot line in grub.cfg.
Maybe reconvert the boot/root device, and if it comes out as ,1
higher than current groot, make the change, otherwise whinge to the
user that the system may be unbootable until the groot is fixed?

(Presumably, that's done in the postinst script. However, update-grub
shouldn't be run, since install-grub hasn't been run and the change
to the groot line in the grub.cfg isn't actually effective until
update-grub is run)

Given that I don't think you can tell where grub2 was installed to
in the first place, detected which version of the grub2 bootsector
stuff is in use would be basically ineffective, so update-grub
can't be relied up.

The only people who'd see this then early-adopters in sid and
etch.

If 1.95 could be snuck into the etch release, then the
list of people who'll get bitten by this shrinks enormously,
but that's something for the grub2 maintainers and the RMs to
decide amongst themselves.

I'd vote for it, since the upgrade process described above is kind of
fragile and that way only people who're expected to be able to deal with
whinging upgrade scripts will see whinges from the upgrade script.

Of course, this'd require updating d-i with the new grub udeb.
I get the impression that's harder than just migrating to etch.
