wrong fstab entry after distribution upgrade
Last modified: 2013-01-10 01:49:40 EST
I did the Fedora distribution upgrade from version 16 to 17 using DVD. I used external USB DVD drive for booting of the upgrade DVD. After the successful upgrade Fedora was not able to boot because Anaconda added this fstab entry:
none /vbusbf usbfs rw,devgid=501,devmode=664 0 0
The boot process failed on step "starting /vbusbf" end falled into the rescue mode.
Please attach the log files from /var/log/anaconda/ on your installed system (assuming you've commented out the fstab entry and booted up).

How did the mount fail? Does the mountpoint exist? Anaconda does not even write out a new /etc/fstab file when doing an upgrade, so this was in your fstab prior to the upgrade. I'm not sure what you expect us to do to in this case.

screenshot of the boot failure
The mount point does exist. I did a screenshot of the boot failure. If I try to do "mount -a" in the living system with this uncommented line, I got:
mount: unknown filesystem type 'usbfs'
I looked at the older logs and it seems that you are right, the system mounted vbusbf before the update too but without failure.
So it seems that it is not a bug in Anaconda. I guess it is related somehow to VirtualBox USB support.
