The second udev is just more rules.
What about parallelizing udev and rc like in moblin ? Any gotcha
there ?
Simo.
What would happen if you parallelizing udev and rc on some ancient
piece of hardware? Im thinking you might not ever get to a boot screen.
But you could check to see what sort of CPU you have and parallelize
conditionally if the hardware can handle it. Conceptually I think
parallelizing this stuff is a novel idea. Its feasible in that its
been done (i.e. the demo). And if we could optimize udev a bit we
might gain a few more seconds there too.
Good topic of discussion anyway...

And how do you know, that an rc script does not need a device, which
is created by udev?
Yeah, there would certainly have to be dependencies in the rc scripts. I
would imagine if one of the rc scripts needed a device, it would be in a
wait state until the device comes up. The mechanism to achieve this
seems somewhat crucial. It will be interesting to discover how Moblin
addresses this issue.
