what does keep old versions or not change besides you need
to do "apt-get update" if you want to find "apt-get upgrade"
to find new packages?

the real problem is that the metadata are *way too fat* in Fedora

after a "yum clean metadata && yum update" on a slow line you
have to wait a very long time and even the download of the
presto-metadata often is larger and takes longer as the
packages which are updated in reality

hey on my 100 Mbit all is nice and fine but on a machine behind
DSL with around 100 KB/Second it is way too slow and large and
i refuse to imagine how this feels on a 56kbit modem
