Is this issue known or do you want a separate bugreport? I'm not the one to ask about separate bug reports, but I notice that with the latest updates, I didn't see the duplicate bind mount: systemd-units-26-4.fc15.x86_64 systemd-26-4.fc15.x86_64 systemd-sysv-26-4.fc15.x86_64 kernel-2.6.38.8-32.fc15.x86_64 Of course if it is timing related, perhaps I was just lucky, but I did get systemd updates at the same time the problem disappeared, so I hope that's a good sign.

I think it may be a timing issue for you, since I have the same updates and I'm still getting duplicates for bind mounts.

There was an update of util-linux. It may have helped. Cristian and Nils are affected by bug 716483. Frank, could you attach your /etc/fstab? Created attachment 510647 [details]
/etc/fstab from affected system.
Attached is /etc/fstab from the affected system.
Frank, you are also affected by bug 716483. Your fstab has the same pattern. I'm closing this bug as WORKSFORME because the problem disappeared for the original reporter and the other reporters are seeing bug 716483 instead. Yep, I just read that report and I agree it looks like the same problem. Thanks. |
