The docs don't seem to tell a user how to get a recent drush version on Debian squeeze.
http://community.aegirproject.org/upgrading/debian refers to squeeze-backports, but there we only have 4.5
What would be the recommended way? Grab from sid? Or install manually?
This info should probably find it's way into http://community.aegirproject.org/upgrading/path#Debian_package_name_cha...
