There's a new feature in Fedora 29, hide the grub menu, that can make it difficult to troubleshoot system upgrades if you run into a problem. Here's what you can do to get more information for a one time boot without obliterating the default behavior you'll maybe want for future testing: - enable a one time show boot menu for 60 second $ sudo grub2-editenv - set menu_show_once=1 - Now do `dnf system-upgrade reboot` - At the grub menu insert the following boot parameter systemd.debug-shell=1 That enables early debug shell, soon after systemd is running. The shell is on tty9, and it gives root access without credentials required! Super powerful, and super duper security risk. So I advise adding it only at the grub menu, for one time use. -- Chris Murphy _______________________________________________ test mailing list -- test@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to test-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://getfedora.org/code-of-conduct.html List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/test@xxxxxxxxxxxxxxxxxxxxxxx
