I looked around, but couldn't find an option that seemed relevant... maybe
I just missed it. I'll look again.

Yeah, did you see my post about /dev/panel ideas? I'd use /dev/panel as
the low level control for a front panel of any description, and then
define an interface mapping machine states/variables to the particular
lights on the panel - things like init would call "/sbin/panelctl --state
running", and panel_state would look in /etc/panel.conf and find:

state running {
	set_led status = power_on

/etc/panel.conf would also contain such gems as:

kernel {
	sched_runq_led = u1
} the scheduler would light u1 whenever a process other than the ideal
process was running, say. /etc/rc would run "/sbin/panelctl --config" to
get panelctl to ioctl() /dev/panel to set up the kernel LED mappings,
which would include states such as "kernel_panic"...
