no, i'm not being facetious. in all seriousness, i'm writing a section for an admin manual on advanced package management (that is, beyond just rpm to install/upgrade/remove), and was wondering what was really necessary beyond advanced rpm operations and yum. there's always the apt/synaptic stuff but, realistically, i don't want to try to cover every possible way to do this. and since it's aimed at admins, a graphical front-end is not critical. so, once someone has a handle on rpm and yum, is there really any compelling need to know about even more package management systems, short of just curiosity? rday p.s. i'm restricting this discussion to RPM-based systems, of course. debian packaging is a totally different issue. i *might* make passing reference to ipkg, but only briefly, in reference to embedded systems.
