I meant specifically the hotkey existing. I clearly can see that hiding the boot menu has its downsides and in fact most of my machines are configured to show it (and I think server actually defaults to menu=on, only workstatiion has menu=off by default). That is doesn't matter much for the uefi/bios and grub2/sd-boot discussion though, both boot loaders can be configured to whatever timeout you like. > 4. Screen flickering and paused screens.

I have a 4k monitor connected to a intel nuc, and grub has a 30s timeout there because it takes *ages* for the screen to sync. And even with the 30s timeout I don't see the menu now and then. The other extreme are laptop panels which typically sync within the fraction of a second where all this is not a problem at all. take care, Gerd _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx 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@xxxxxxxxxxxxxxxxxxxxxxx
