Description of problem:
Fedora Upgrade via DVD from 16 to 17 fails. After some analysis, I found that my system had a CIFS file system in its fstab that was not mountable at the time of the upgrade.
When I commented out the CIFS filesystem(s) from the fstab and rerun the upgrade it worked fine.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1- Add a CIFS file system in the /etc/fstab that is not mountable:
//192.168.8.33/v-drive /v cifs username=vpi-us/linux,password=something 1 1
2 - When you run the upgrade it will hang/fail.

This also happens when an ISO file is specified as the device, mounted with the "loop" option. Also, I was unable to submit the bug with the built-in bug reporting system, because the reporter triggers a new exception, apparently while gathering information about the system state.
We now ignore unknown fstab entries.
