Hello again,
it looks like /dev/xvda1, where the Xen system is booted, is a special case and
that in contrary to the other devices, like /dev/xvdb, etc., it can not be
modified.
The problem is therefore that part of the toolchain does not recognise in
advance that it is impossible.
Do you think that partman can or should obtain this information by itself, or
that this bug should be reassigned to another package, which would be in charge
of issuing an error message that partman can understand, to make sure that
debian-installer does not assume that the disk has been partitionned
successfully ?
