However running grub2-mkconfig to generated a new grub.cfg file that appears to work properly. The source of the trouble appears that when the kernel is upgraded a new grub.cfg is created with an incorrect UUID for the root device; this UUID doesn't appear to have any connection with the UUID of any device on the system. More to follow if I have trouble with the next kernel upgrade. jon -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
