(Ah, the fact I'm dealing with essential packages may have warped my
evaluation of the situation somehow)
However, it does say:
The specific form assigns a priority (a "Pin-Priority") to a
specified package and specified version or version range.
And:
The general form assigns a priority to all of the package versions in
a given distribution (that is, to all the versions of packages that
are listed in a certain Release file) or to all of the package
versions coming from a particular Internet site, as identified by the
site's fully qualified domain name.
I think it could be made more clear then.
Does "specific/general" refer to the "single package name" vs. "*"
aspect of the example, or to the "version/release" keyword ? The fact
that examples does not allow to disambiguate seems annoying to me.
The fact there is an "origin" keyword as well would advocate for the
1st alternative. BTW, this "origin" keyword is not documented, apart
from being mentionned as existing and being different from "release
o=...". You may want to address this as well - I don't think it's
worth openning another bugreport ;)
