None of those things require us to write data to /boot. Even in your model, if you *must* write to a filesystem, the counters can live on the ESP even if all the system-installed content exists in /boot. I'm sure you could envision a simple file in the ESP for that. None of that is permanent configuration, just transient stuff. > I am sure Neal Gompa can recover his own machines, but not every > Fedora system comes with a Neal Gompa deployment included. > Okay, if you're going to be a jerk about it, no Fedora system comes with a helpful version of Lennart to work out problems people encounter with this stuff. -- 真実はいつも一つ！/ Always, there's only one truth! _______________________________________________ devel mailing list -- devel@lists.fedoraproject.org To unsubscribe send an email to devel-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
