playing with fedora these few days.

yum is great with it's delta package system. which only download changed file instead of the whole package.

one thing i dont like is that yum do not know what dependencies have been installed and should be removed.

debian aptitude works out of the box.
and we can add --auto-orphans to mandriva urpme


some people suggest 'package-cleanup --leaves' to list leaf node (package that no other package depends on).

i try that, and it list libvirt which is needed by virt-manager. so i cant fully trust that.

more googling i found yum plugin remove with leaves package.

su -c 'yum install yum-plugin-remove-with-leaves'
yum remove --remove-leaves package-tobe-removed

still need to test this
