[Pkg-uml-pkgs] Bug#621103: /usr/bin/uml_moo: uml_moo: doesn't allow block devices as backend

[Ph. Marek]

Package: uml-utilities
Version: 20070815-1.1
Severity: normal
File: /usr/bin/uml_moo

I'm using a block device (lv) as backend device for user-mode-linux.

uml_moo won't let me merge changes back:

$ uml_moo -d base.cow
Size mismatch (6442450944 vs 0) of COW header vs backing file "/dev/vg/deb1"


In case of a block device the device size should get compared, not the size of
the device inode.
