How can I know? :) I started this back in March this year and just give
it a second try now with this much improved version.

We are run into serious trouble with HAL(hal.freedesktop.org) managing
the unordered events from the programs in /etc/hotplug.d and /etc/dev.d/,
to match these two events together by SEQNUM and wait for sysfs to get
populated. This all should be pretty easy now with only one small
hal-notify program in the /etc/hotplug.d directory.

Let's see what other people think about it.

Thanks,
Kay
