Package Portable Server for Red Hat OSes

[tst-ppenev]

As a user, I would like to be able to install Portable Server from a Red Hat package, or from an EPEL repository.

AC:

• Add a build script that produces a Red Hat package with Portable Server for the architecture you are building on. (64-bit x86 should be supported.)
• The package should add a service that could be added to a run-level.
• The service should be configurable from files under .
• A non-root user should be able to start the server from the command line, without running the system service.
• The package should install on recent versions of RHEL (to be clarified).

We should probably split this ticket up. The original portable installer didn't support configuring as a service, so I think that should be split into its own ticket.
