Chakra: the best release model.
I don't get why distros don't copy the Chakra model.
1. Kernel, X, boot scripts and STRICTLY CORE stuff: they stick to STABLE versions, hammered until the end, working with everything. The versions you see of those packages in Chakra are not current, even old (GCC is at 4.5.3 with Chakra, Fedora 15 is at 4.6.1)
2. Apps: they are updated, literally, TO THE MINUTE. Actually, if I enable the Testing repo, I can have a KDE release hours BEFORE the official announcement.
3. Package Manager. The Chakra package manager, Appset-Qt, does not only manages packages; it manages INSTRUCTIONS TO MAKE THOSE PACKAGES WORK. So, you always see a channel with those instructions when you open your package manager. That is PRICELESS and MUST BE COPIED BY EVERY DISTRO.
