That's simpler than distributing an RPM to the repos, by a long ways. With that
approach, all we'd need would be the spec (build) script. I append the example
at the end of this email. As you can see, it's not very much. I'm sure it could
be better written (I'm no RPM "maven" {grin}) but it's a place to start. I used
the Tanuki Java wrapper as part of the dependency, because that software is
commonly available for almost any Linux distro. I also included a separate
body of source for the package (shown below as "wrapper-gear") which is just
the files that Karaf creates from its "wrapper: " commands. These two
inclusions allow the RPM to install Karaf as a Linux system service using the
Tanuki wrapper.
Graham-- I'll send you a tarball of "wrapper-gear" off-list, just so you can
see what I did.
It's this worthy of opening an issue?
