Bug#644166: /usr/bin/apt-get: apt-get -t no longer supports generic Release tags such as o=
Package: apt
Version: 0.8.15.8
Severity: normal
File: /usr/bin/apt-get
apt-get used to allow specifying tags with "-t" which are not release
names, but are tags found in a release file, as supported by the priority
engine and /etc/apt/preferences.
For instance, apt-get install t="o=Debian Mozilla Team" lets me choose
packages from the current Iceweasel backports, or -t "o=Wine Sid
Repository" for the upstream wine repository.
This no longer works in testing. The message emitted is
E: The value 'o=Wine Sid Repository' is invalid for APT::Default-Release as such a release is not available
in the sources
I guess therefore that this loss of functionality is a side-effect of the
fix for #407511 which limits -t to actual Debian release names. It was
very useful to be able to effectively override any pin in this manner.
If the functionality can't be restored to -t, please can some other option
be added to allow the policy overrides mentioned in apt-get's man page ?
