That should not happen. There is an exception for dmraid devices, which 
apparently no longer works.

From the output you provide the reason seems to be that partitions are now 
created as <dmraid dev>p<partition nr>. The problem is the "p" between 
the device and the partition number which AFAICT did not use to be there 
before.

This makes the "isinstallable" test fail for grub-instaoller. I would not 
be surprised if this would make other changes necessary too.

First thing that needs to be determined is what exactly has changed to add 
this "p". Is it a change in dmraid, or in libparted, or elsewhere?
When we know that we can check where changes are needed.
Do you have any idea yourself where this "p" comes from?

dmraid has never been tested with lilo, so this is not very surprising.

I'm reassigning this issue to partman-dmraid as that is the most specific 
component for dmraid support, even though most needed changes will 
probably be in grub-installer.

Cheers,
