That's essentially correct, although I don't think the inconsistency is
a major one. The core certification remains distribution-independent; a
candidate who passes the new 103 test will simply be demonstrating
additional Ubuntu-specific knowledge. It's possible that people might
perceive a weakening of the core philosophy of LPI, but I think that's
more a perception than reality.

Those aren't distribution-specific. RPM is used by SuSE, Mandriva and
many other distributions, and is a requirement of the Linux Standards
Base, which is why it is supported even by Slackware, these days (though
Slackware honours it more "in the breach", as they say). Similarly,
other distributions have used the Debian tools, although these days,
both camps rely more heavily on front-end tools like yum, etc.
The decision was taken in the early days to avoid distribution-specific
tools and focus on generics. However, software installation and package
management was a sufficiently important area that it couldn't be
ignored, despite the fact that there was no single generic package
manager for all distributions. So the decision was taken to deal with
the two major alternatives, so as to not disadvantage any large single
According to archived emails I have from back then, this is the only
area in which LPI certification makes any concession to variations
between distributions. Everything else has been kept as generic as possible.
