We just noticed that Pungi is putting the i686 kernels in the x86_64 install trees: https://dl.fedoraproject.org/pub/fedora/linux/development/rawhide/Everything/x86_64/os/Packages/k/ https://dl.fedoraproject.org/pub/fedora/linux/development/branched/Everything/x86_64/os/Packages/k/ this causes anaconda to install the i686 PAE kernel in x86_64 installs, and that doesn't work out too well. The fact that anaconda prefers a kernel for i686 if it's available is probably also a bug, I'll file another bug against anaconda and have them reference each other. This obviously results in the installed system failing to boot: https://openqa.fedoraproject.org/tests/7017 so proposing as an Alpha blocker bug (either this or the anaconda bug should be the blocker, I'll propose both and we can sort it out later).
Discussed at today's blocker review meeting [1]. Removing blocker nomination, because we accepted bug 1315434 as a blocker, which is a superset of this. Either this bug or bug 1313957 needs to get fixed. [1] https://meetbot-raw.fedoraproject.org/fedora-blocker-review/2016-03-07/
The problem is in the compose configuration: the package names are tested against patterns in the blacklist using fnmatch. However, the way the config is currently written it passes in regular expressions.
The pungi configs have been fixed. closing this as current release
