The topic of tracking multiple releases came up at last night's HOSEF workshop. I am sending my boilerplate configuration to the list for archival purposes.
More information can be found at the man page for apt_preferences(5) and http://www.argon.org/~roderick/apt-pinning.html. The Pin-Priority entries in my example are a bit arbitrary and differ somewhat from the link above. -Vince /etc/apt/apt.conf: APT::Default-Release "testing"; APT::Cache-Limit 12582912; /etc/apt/preferences: X-comment: ===== Testing ===== Package: * Pin: release a=testing Pin-Priority: 700 X-comment: ===== Stable ===== Package: * Pin: release a=stable Pin-Priority: 70 X-comment: ===== Unstable ===== Package: * Pin: release a=unstable Pin-Priority: 80 /etc/apt/sources.list: deb ftp://videl.ics.hawaii.edu/mirrors/debian stable main non-free contrib deb ftp://videl.ics.hawaii.edu/mirrors/debian testing main non-free contrib deb ftp://videl.ics.hawaii.edu/mirrors/debian unstable main non-free contrib deb http://http.us.debian.org/debian stable main non-free contrib deb http://http.us.debian.org/debian testing main non-free contrib deb http://http.us.debian.org/debian unstable main non-free contrib deb http://non-us.debian.org/debian-non-US stable/non-US main contrib non-free deb http://non-us.debian.org/debian-non-US testing/non-US main contrib non-free deb http://non-us.debian.org/debian-non-US unstable/non-US main contrib non-free deb http://security.debian.org/ stable/updates main contrib non-free
