ok, waiting for it to happen again. when i was ready to shutdown both my vivid boxes last night i just flipped off their powerstrip switches without logout nor shutdown. this morning, no FSCKs. whatever triggers them, that's not it.
maybe time discrepancy, if the last OS running had the wrong time? there are open bugs re booting up with the wrong time, eg Bug #1335522 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1438824 Title: ALL FSCKs triggered for no apparent reason To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1438824/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
