F29 hidden GRUB, problem testing and how to unhide
I've got a Fedora 29 Silverblue installation in a VM. First boot I see
the GRUB menu, and after that it's hidden. And I can't figure out how
to unhide it. Boot is failing before I get multiuser login or ssh, so
extracting information to troubleshoot/bug report isn't possible.
Repeatedly pressing or holding Esc doesn't work.
Spacebar doesn't work.
F8 doesn't work.
So now I'm stuck. Yeah, I can reinstall, and before rebooting make
sure whatever is hiding the GRUB menu is disabled, every time I do
installations. But the very reason why people were so vocal about this
feature not happening is exactly this use case.
This is a Fedora 29 host. Fedora 29 (silverblue, maybe it happens with
Workstation as well) as guest. Virt-manager is what I'm using for
interacting with the VM.
