Do you mean that /etc/fstab keeps reverting from DK1 to your DK0 root? Or to phrase that question differently: if you fix the error in /etc/fstab, are new kernel updates still added with a DK0 root= parameter? Theoretically, you can boot to an older kernel, erase the latest one and reinstall it for testing. What is located on DK0-root? When running DK1 root, does os-prober generate any boot entries for the DK0 root? And yes, if you think that doesn't answer your question, I haven't seen the missing details yet, such as: Is this a fresh install? When did the symptoms occur for the 1st time? And the answers to above questions. Too much guess-work needed so far. Clearly if /etc/fstab is wrong, that bears a risk of propagating into grub.cfg or boot-related files. -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
