Bug #12448
loader: improve boot options for kmdb and framebuffer
100%
Description
I seem to be spending quite a lot of time talking people through dropping to the loader prompt and configuring nmi=kmdb so that it is possible to drop into kmdb by sending an NMI. Similarly with the framebuffer I've had to talk people through dropping back to the old plain VGA console mode.
The loader boot option screen could be improved to make these things easier.

I have a persistent switch "reconfigure" enabled on my system.
Is there a way to have "framebuffer off" persistent as well? Is it documented (i didn't find it with man loader etc.)?
Greetings,
Stephan

To persistently disable the graphical console, create a file in the installed OS called /boot/config and put -t in there.
The available options are documented in the man page for gptzfsboot

Hi!
I build, published and installed the Change,
and i really like it!
On my system tthe framebuffer variant is very slow (4k uhd display with nvidia quadro M1200 gpu),
and the non-fb VGA variant is fast as it was in the 90ties ;-)
Thanks!

Tested extensively with the upcoming r151034 omnios release on legacy and UEFI boot systems, cycling through the kmdb options and booting in VGA text mode.
