Reading versionmatch.cc it seems that specifying
Pin: release unstable
means that either the codename or the archive is unstable. This probably
is not well-documented, but it is there.
Relevant parts are:
ll. 57:
// Are we a simple specification?
string::const_iterator I = Data.begin();
for (; I != Data.end() && *I != '='; I++);
if (I == Data.end())
{
// Temporary
if (isdigit(Data[0]))
RelVerStr = Data;
else
RelRelease = Data;
ll. 200:
if (RelRelease.empty() == false)
if ((File->Archive == 0 ||
stringcasecmp(RelRelease,File.Archive()) != 0) &&
(File->Codename == 0 ||
stringcasecmp(RelRelease,File.Codename()) != 0))
return false;
