Updating from F16 to F17 lead to a fatal error:

The following was filed automatically by anaconda:
anaconda 17.29 exception report

DeviceError: ('device has not been created', '//10.0.0.203/cri2011')


The problem is that the following Windows share entries in /etc/fstab were not ignored:

//10.0.0.203/cri2011 /mnt/IASMA003_NEWCRI cifs user,iocharset=iso8859-15,credentials=/etc/samba/auth.10.0.0.203.netelerm,uid=neteler,file_mode=0664,user_xattr,dir_mode=0775 0 0
//10.0.0.203/SCAMBIA /mnt/IASMA003_SCAMBIA cifs user,iocharset=iso8859-15,credentials=/etc/samba/auth.10.0.0.203.netelerm,uid=neteler,file_mode=0664,user_xattr,dir_mode=0775 0 0
...


Solution:
I copied the /etc/fstab file to /etc/fstab.mybackup, then removed the entries from /etc/fstab and rebooted to successfully upgrade the system.
