rpcbind is enabled by default, and gnome-boxes requires it

[Andrew Lutomirski]

I don't know whether this should be a gnome-boxes bug, an rpcbind bug,
or a FESCo ticket, or something else, so I'm asking here.

rpcbind enables itself by default.  This page says that it has a
specific exception, so it's okay:

https://fedoraproject.org/wiki/Starting_services_by_default

I assume that the exception comes from the idea that server systems
probably want it on if they've installed it.  That may make sense in
some contexts.

Alas, libvirt-daemon-kvm requires libvirt-daemon-driver-storage, which
requires nfs-utils, and nfs-utils requires rpcbind.

gnome-boxes, in turn, requires libvirt-daemon-kvm, resulting in this:

tcp        0      0 0.0.0.0:111             0.0.0.0:*
LISTEN      774/rpcbind
tcp        0      0 0.0.0.0:20048           0.0.0.0:*
LISTEN      887/rpc.mountd
tcp        0      0 0.0.0.0:875             0.0.0.0:*
LISTEN      930/rpc.rquotad

*on my laptop*

IMO this is bad.  Should I file a FESCo ticket asking to revoke the
rpcbind and nfs-utils exceptions?  Should I file a bug against
libvirt?
