these packages should come post-5.4. Are you only updating select
packages? why not update everything?

Depends on what you need.

In short, each instance needs its own resource (e.g. ports/sockets,
log files, etc). There are ways to do that manually (e.g. editing
radiusd.conf, customized init scripts, etc.).

If you have no idea what I'm talking about, I actually suggest you
just use virtualization. lxc, in particular, has very little overhead,
and depending on your skills, managing multiple virtual environment
might be easier than managing several customized FR instances.
