    The same benefits you have from compiling from source to /usr/local.
    You don't break anything already existing in the distribution and
    you don't lose the ability to get updates to anything from
    the distribution.

    Yes, as a side effect you could still run the stock package if
    you wanted, but that is probably less useful than the fact that
    you would not have introduced RPM dependency conflicts that
    keep you from doing updates.

    By 'conflicts', I mean has the potential to introduce dependencies
    on different versions of the same-named packages. As long as everything
    is compiled in the same environment that won't happen. If a 3rd party
    repo replaces a stock library with a different modification and has a
    package that depends on it, what is supposed to happen when the
    distribution releases a needed update to that library and package
    updates that depend on it? There is usually no equivalent problem if
    you compile extra stuff from source and keep it all under /usr/local,
    including non-standard libraries.

    And no replaced stock RPMs? Can you be sure that it will still
    be stable regardless of what is pulled from the distribution's
    updates?
