udev_start and no SCSI devices

udev_start and no SCSI devices

[Jon Smirl]

I'm using Fedora core 3 and udev. udev is taking 30 seconds to start.
I tracked it down to something to do with SCSI support. I don't have
any real SCSI devices, but I do have SATA drives and a CD writer. The
problem seems to be with a queue_type of "none". It's the HOTPLUG scsi
script that is hanging. The device on host0 is a SATA disk.

Adding some debug to start_udev I see this:

[root@jonsmirl sbin]# ./start_udev
Starting udev:  /sbin/hotplug
