anaconda or systemd creates swap partition/file values in /etc/fstab with a wrong pri value. in /etc/fstab it shows as uuid=.... swap swap pri=-1 0 0 on the other hand after system reboots systemd's fstab-generator gives error and not enables swap. ( So if you didn't edit your /etc/fstab and change value to uuid=... swap swap defaults 0 0 you will have a DISABLED swap ) Why fstab-generator couldn't handle swap ? Because it is not programmed for getting a negative value as pri parameter. Thus in logs it says : systemd-fstab-generator[16571]: Failed to parse priority: Numerical result out of range systemd's fstab generator is checking if pri exist or it is between 0 - 32767 so if we delete pri=-1 part from /etc/fstab it will be not a problem for fstab-generator ( pri is optional ) PS : Bug reported as #1204336 -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct
