Bug#545224: grub-pc: No Option for Lenny+GPT+Xen stable

[Ian MacDonald]

Package: grub-pc
Version: 1.97~beta3-1
Followup-For: Bug #545224

We have been using a recipe Lenny+RAID+Crypto+LVM+Xen+iSCSI with quite a bit of sucess on legacy servers with large disks.

1.0TB, 1.5TB were not an issue.  Now with 2.0TB and larger, we are facing GPT parititioning forcing us away from grub-legacy. 

Following issues worked around for automatic updates in grub.cfg (http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=505517), we are now faced with this issue of Xen not booting.

We have no packaged options in backports or upstream squeeze(our current grub) or sid that deal with this issue. 

Once the debian installer is corrected to handle GPT (5.0.3 has issues - http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=548156) we expect all new xen setup on large disks to get stuck right here.

Xen on Debian stable is one of the strongest backoffice solutions we have, so we are hoping this is resolved through xen-kernel-devel or grub-devel somehow.  Let us know how we can help :)

cheers,
iMac
