automatically enter boot interrupt

[Paul Senior_1]

I've heard there is a keystroke you can enter before the boot interrupt stage which causes an automatic boot interrupt once that stage of the boot is reached.
i.e. so you don't have to stand over a slowly rebooting machine waiting for the boot interrupt

[Luk Vandenbussche]

You can do it with the command setboot before you reboot the server

setboot -b on /off

See also : man setboot

Hm, I'm not really aware of this.

There was something similar on old K- and D-class servers - pressing CTRL B to get a special console (don't remember the name of this). Once the server reaches the console, it waits until you go back to the console (CO).

This no longer works with current servers.

Only way IMHO is to disable autoboot (see setboot) prior the shutdown.
