i am using stable,testing and unstable repositories to get up to date packages.
and i am using Debian squeeze,
lets say if i want to upgrade my Debian from 6.0.4 to 6.0.7 only from stable. then how i could do it?
actually i am confused a bit, lets say if i run "apt-get upgrade" and i have all the level of repositories, will it be upgrading from all the repo? what i want is to upgrade the OS only from stable however in future if i want to use any upgrade package then i could also use testing and unstable repositories with out changing /etc/apt/sourcelists and running the command "apt-get update" all the time.
