Others might provide more detailed information, but here's a summary:
Because - at least for Fedora 9 based builds - yum requires more RAM
than is available on XO-1. In at least some of the cases, it won't work
properly, but still continue (leaving the user to believe everything
went fine).

The Debian package management tools work fine on XO-1. I've only ever
had trouble with a single package - locales - that required more RAM
than was available. It caused the upgrade to abort in a not exactly
user-friendly way, but arguably better than going on as if nothing had
happened. This particular case is easily avoided by using precompiled
locales (package locales-all) instead of compiling them during package
installation (package locales).

More recent versions of yum might be better in one of or even both
regards: Transaction support might fix the "go on as if nothing
happened" issue. Memory requirements might have improved as well.
Hopefully some of the Fedora folks will elaborate on this (all I
wrote is from my personal experience as a user).
