Description of problem: I have brought the system complately current. mount -a will mount /boot but systemd fails to do this causing all sorts of headaches. Version-Release number of selected component (if applicable): systemd-44-17.fc17.x86_64
Please attach your /etc/fstab. Please attach a log produced using these instrutions: http://freedesktop.org/wiki/Software/systemd/Debugging#If_You_Can_Get_a_Shell
Some change in software or cleaning up the crap that was in the mount point (files created when the point wasn't mounted) seems to have fixed it. The last reboot mounted /boot properly. I may have this happening on another machine. I will try to reproduce it there. The machine this bug was reported for does very long run processing jobs (months to years) so it is unlikely that it will be down and able to test again. (Power went out. Yes, it should be on a UPS, but I am having trouble finding one that works well with high effeciency power supplies.)
OK, closing. Feel free to reopen if you can reproduce this issue so that we can analyze.
