There is a definition, but it's quite tough:


in practice, the net is cast somewhat wider at GA time, but we don't
have a hard definition.

We've been trying to work to a hard definition at least for Alpha:
considering bugs that significantly affect the critical path (see
https://fedoraproject.org/wiki/Critical_Path_Packages_Proposal ) as
blockers. The definition of 'significantly affect' is basically
'severity high or urgent according to
https://fedoraproject.org/wiki/BugZappers/BugStatusWorkFlow#Severity ,
but there are exceptions to this:
https://bugzilla.redhat.com/show_bug.cgi?id=515410 is one, it's
technically medium or even low severity, but practically it would cause
severe surprise to _everyone_ installing the Alpha, so we consider it a
blocker). To give a short definition without references: if it stops you
being able to install, get into a graphical desktop, or update the
system, it's a blocker bug.

We're trying to get to a decent solid public definition of blocker
criteria for each release stage, but in practice it's very hard to write
a policy that's both definitive yet sufficiently flexible to cover odd
cases. I'm not sure we'll ever get all the way there, but we'll do our
