If you are running the kernel that works that won't be removed by this
plugin. If lot of kernels don't work the problems lie elsewhere.

Note that both of these are just a matter of default preferences and can
be easily changed. The large majority of end users don't use dialup and

have no requirement to save installed packages on the cache.


The "installonlyn" plugin is probably better suited to RHEL, not
Fedora Core. I do not have a RHEL license but my take is that RHEL has
fewer released kernel updates than a developmental product such as
Fedora Core. If the goal of Fedora Core is to test various packages it
really makes no sense for the testers (that's the entire FC user base)
to have stable or reference kernel packages pulled out from them.
