Probably true most of the time. But it depends on the defect. It is true that there's some small metadata space that isn't tested because it's taken up by the file system itself but if that corrupts, chances are you'll see weird problems during the read. Or you can just use Btrfs which will unambiguously tell you of an error in metadata locations that aren't covered by the test. > > Well it's a bit needle in a haystack trying to track down transient > > boot problems. > > Well I certainly understand the problems with flash.

This is about as many boot failures as I've seen on the test list in quite a while though. -- Chris Murphy _______________________________________________ test mailing list -- test@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to test-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/test@xxxxxxxxxxxxxxxxxxxxxxx
