It may not be a best practice, but I can't think of anything that
actually breaks - or is even an issue on a small private network - if
you overlay subnets on the same wire. VLANs are a nicer approach but
then you need a more expensive switch and if the Linux box is on a trunk
connection you have to find some elusive documentation about how to
configure subinterfaces.
