Bug#588026: lvm2: Missing breaks for grub2

[Helge Kreutzmann]

Package: lvm2
Version: 2.02.51-2
Severity: important
Tags: patch

I have a laptop I irregularly use. Before departure (usually offline,
like travelling), I "apt-get -d dist-ugprade" and then install the
package offline. On my last trip, suddenly grub-probe broke the
upgrade, claiming not to find the root device (which was clearly
there, on encrypted lvm). If needed, I can provide you the exact error
message.  I invested quite some time assuming a local configuration
error but to no avail. Once I had network again, I discovered that
this is an error in grub2, which is fixed in 1.98+20100527-1 in grub2
(as of #550704) but this version is still not in testing (which I
use).
So the current combination of lvm2 and grub2 does not reliably work.

So please add a
Breaks: grub2 << 1.98+20100527-1
to debian/control to prevent grub2 users from updating lvm2 *before*
grub2 (as the situation currently in testing or partial updates).
