Package: apt Version: 1.6~beta1 Severity: wishlist
Hi! It would be nice if you could document, preferably by an example, how to affect _all_ possible copies of a package, no matter where they come from. This is useful in at least two cases: * someone wants to prevent a package from being installed despite notorious Recommends (bash-completion, a *cough* certain init implementation, etc) * someone wants a particular _architecture_ kept from being installed I just had the latter case: x32 doesn't ship its kernel but uses one from amd64 (similar to i386, except that there's no "native" kernel at all), and the kernel package keeps insisting on replacing native irqbalance, apparmor and so on with :amd64 versions. Too bad, the documentation is lacking (or perhaps it's me not reading it well enough), and I wasted quite a few minutes looking how to produce such a rule. Turns out, a missing Pin: line doesn't work, neither does "Pin: *". You need to pick a dummy but valid field, and asterisk that. Ie, "Pin: origin *" or "Pin: release *". There's also no mention that you can limit the rule to a specific arch, but fortunately my guess was correct. Thus. please include one of the following examples: .---- Package: irqbalance:amd64 Pin: origin * Pin-Priority: -1 `---- which blocks irqbalance:amd64 but not irqbalance:x32, or .---- Package: libc6:amd64 Pin: origin * Pin-Priority: -1 `---- which is a big hammer that blocks all regular foreign userland code, allowing the kernel and static stuff.
