Yes, I think it was Doug Ambrisko who put in the shims for that, but
haven't tested it.
And yes, megarc should be on wikipedia as a bad example for bad interfaces.

For the hourly job, there is a function in the amr(4) driver that's
supposed to do a constant check of the controller but alas the
function is just declared, empty in function. If this was to work, a
message to syslog would be enough to send out an email with an alert
I started this weekend(again) my port of bio from OpenBSD and I really
like what they did with the sysctl variables and with sensorsd like:
$ sysctl hw.sensors
hw.sensors.0=sd0, ami0 0, drive online, OK
hw.sensors.1=sd1, ami0 1, degraded, WARN
hw.sensors.2=sd2, ami0 2, failed, CRITICAL
With sensorsd on top of that, monitoring is a breeze.
I think after bio I know what I will do next ;-)
