Does it matter what source package you use?

dpkg-source: extracting ssh in ssh-1.2.26

Although NFS here isn't super reliable (I often get errors "rm /tmp/*:
Device or resource busy", especially when running dpkg --info), the
above works fine here; all directories are NFS mounted:

The NFS server is running Linux 2.2.2, and the client is running
Linux 2.2.1
