I am not sure if Gentoo or Debian even have 'point releases', at least
in the sense that RedHat has done things since way back when.

No, you you really should run yum update more frequently.  Every 6
months (or so), 'yum update' will automagically upgrade to a point
release. I am not really sure it really makes any sense to stay at a
given point release, esp. sice point releases are not some sort of
major new version or anything -- they are more a consolidation of many
small updates bundled together has a kind of 'update milestone' and are
more a matter of being a conveinent place (in 'time') to burn a new
batch of iso images.
