Why Arch Linux?

[Kyle]

As a rule, Arch packages always update to the latest version. However, 
all the PKGBUILD scripts are available from the ABS (arch build system) 
tree, and you can always setup a local repo to maintain binary packages 
for whatever version you like. I believe there's even a way to make your 
local repo override the official repos for any package you have 
regardless of the version, but I'm not absolutely sure about that. You 
can, however, hold any package at the version you want to keep for as 
long as you want.
