Reset it to 1 for each devd config file so if the parser finds
a syntax error devd(8) will report a correct line number.

devd doesn't use get*by*() which is one of the main motivations for
dynamically linking your root partition anyway.

Also, put a small work around into devd to prevent a hang on boot this
would cause because select used to return 2 rather than 0 for no
evetnts due to a bug I fixed a few days ago in subr_bus.c. I'll
remove this workaround May 7th. You have until then to upgrade your
kernel if you want to run a new devd with an older kernel.
'd': now means don't do daemon().
'D': Debug
'n': Don't wait to process all pending events before calling daemon.
In the past, devd would call daemon immediately. However, this causes
a race. If anything in the boot process depends on configuring the
devices configured by devd, maybe they would be configured in time,
maybe not. Now we don't call daemon until all pending events are
processed, unless -n is specified.
# -n is actually the default for a while due to the select(2) bug in devctl
# that I just fixed to give people a chance to upgrade.
to 0 when we startup. Print a warning in this case. This allows
people that are playing with devd by hand to have something happen.
Otherwise, it appears that devd isn't working because /dev/devctl is
disabled and producing no events.
