Package: nbd-client
Version: 1:2.9.9-6
Severity: wishlist
Tags: patch
the following patch provides the ability to specify just the nbdport at
the boot prompt, and getting the server ip address from DHCP. this makes
it possible to server the same read-only image on multiple networks
without having to configure boot options on all machines.
