Experimental Physics and
Industrial Control System

I don't know how you're doing it, so I'd be very interested to hear if
you have time to briefly share.  But I would guess one or more of the
following makes it work for you:

1. Users only use the command line tools that come with EPICS.

2. Users don't compile any programs that link with the libraries
   provided in your EPICS binary packages, nor do they create any binary
   packages of their own that depend on your binary packages.

3. When you say "EPICS as binary packages," you mean only what has
   been in the past referred to as EPICS Base.  You do not mean EPICS
   modules.

4. You provide binary packages for EPICS as well as EPICS modules, and
   you build them all at once from the same source, and to upgrade, a
   user must upgrade all of the binary packages at once or none of them.

5. You provide one monolithic EPICS binary package that includes EPICS
   and all EPICS modules.

I'm not saying all of these will be true, but I think some or parts of
some of them must be true in order for it to work for you.  I'd be very
interested to hear how you have made things work using a binary package
management system.
