Doch, bei der Version aus Testing schon. Einfach die Source Pakete
holen und bauen - fertig

Ich auch, ich auch! Sind allerdings gerade erst im Entstehen und an
der ein oder anderen Stelle vielleicht noch nicht ganz rund ;-)

Ich hab 3 Gruppen, eine mit Pakete die es eilig haben, eine für
normale Pakete und eine für unwichtiges. Die Idee war es Online Spiele
weniger anfällig gegen anderen Traffic zu machen. Es funktioniert so
weit dass ich mit wget die Kernel-Sourcen ziehen kann und meine ping
Zeiten kaum einbrechen.
