That's mostly udevstart + async mode + the (really much improved)
coldplug support I proposed some days ago :-)
Though, it would have been nice to announce you'd handle that in the
previous "USB coldplug" thread, it looked like you were not in favor
of pushing such bus coldplug support.

I'd still like a --disable-bus= option so that distro vendors can
forbid bus coldplug they don't like.
I'm not sure most distro are ready to have udevstart automatically
load modules on the pci bus. For example network and sound drivers are
often handled separately.
Should I take care of this patch?

And why not keeping the udevstart name? The previous udevstart can be
replaced by this udevsynthesize. They fulfill the same tasks, the only
difference is async mode + bus coldplug, does it justify a name
change?

BTW, it's nice to see you've synthetized most useful bus-specific
environment variables, nice work.

Good job!
