Comment 1 for bug 14792

autofs Recommends nfs-common (which, in turn, depends on portmap). I
assume this wasn't set as a strict dependency because autofs can automount
just about any filesystem, and certainly wouldn't need portmap/nfs-common
to do so for anything other than NFS.

That said, a quick conversation with a few people led to the general
concensus that autofs really isn't often used for anything other than NFS,
and a dependency on nfs-common certainly doesn't seem too far out of line
for a package like this, so I'll upgrade the Recommends to a Depends for
the Ubuntu fork of the package.
