Hello, We just patches some of our production Wheezy machines and encountered this bug as well. In our testing on systems where there's only one PV in the VG the root device is the /dev/mapper version in grub.cfg. On systems where there's more than one PV in the VG grub.cfg gets the UUID of the device which renders the system un-bootable.
We're using the fix of setting GRUB_DISABLE_LINUX_UUID="true" too but I suspect this is severe enough it should be fixed in Wheezy, shouldn't it? We have multiple dev hosts in vmware we can use to provide more information if need be. Thanks, Keith. -------------------------------------------------------------------------------- This information is directed in confidence solely to the person named above and may contain confidential and/or privileged material.
