The packages are categorized according to their stability.
- stable packages imply minimal
upgrading risk. They are considered very well tested.
You will usually find slight modifications to Red Hat's own packages
here.
- good packages have been working very
well, but there hasn't yet been enough third party feedback to judge
on more setups.
- testing packages are provided on a
"works for me" basis.
- bleeding packages means asking for trouble!
- obsolete packages will be removed soon.
The stable, good and testing packages are enabled by default in
apt-get and yum. bleeding packages can be
enabled in the respective configuration files, while obsoleted
packages are offered only for manual download.
