Sometimes you want to disable the console blanking out, because let's face it, we're mostly using headless servers now.

This seems to be a deeper terminal setting, and not so much a matter of invocation of the getty app itself. Given that, it's a little tricky. Everyone says to just run setterm from your bashrc, but that's not so helpful when NOBODY LOGS IN ON YOUR DAMNED VTs, MOSTLY.

Query with cat /sys/module/kernel/parameters/consoleblank, I don't know how/why this works if it's meant to be a per-VT thing.

1. You can pass a kernel commandline option, should work well but feels like overkill. GRUB_CMDLINE_LINUX_DEFAULT="quiet splash consoleblank=0"

2. Put the magic control code inside /etc/issue, because pretty much everyone dumps that to the VT when it gets kicked into action. Super janky but should be perfect: TERM=linux setterm -blank 0 >> /etc/issue

This is really all setterm is doing, which is why you can pipe-append that to /etc/issue: echo -n -e "\033[9;0]"
