I like to get the expected behavior up front, then explain the ramifications. Maybe it helps people who are just skimming retain the info. ie: "To make sure any extN filesystems that might be reused or resized are healthy, the Fedora installer automatically performs a check on filesystems it discovers. If this check takes a long time, perhaps because of large, slow, or damaged filesystems, the installer may..."
The expected behavior is fsck should run only on volumes that are explicitly set to be resized. Instead, all ext volumes are fsck'd pretty much right away.
Or, are you asking for it to be included in the RNs?
No just http://fedoraproject.org/wiki/Common_F21_bugs I think is OK?
