Without being logged in there's very little you can do on a host right now, and sysrq should not open up more there by default.You must have forgotten your university days.... The alternative to not being able to sync-umount-boot using sysrq is to flip the switch. I'd rather have them use sysrq. I said it when they closed X ctrl-alt-backspace and I'll say it now. When you are on console with the power plug, preventing these actions is stupid
when you are on a machine where you have pysical only keyboard and mouse it is not - not every PC stands in front of your face - think about kiosk mode and so on...
