Puppy uses a very small initramfs that does not use udev. We use udev
after a switch_root to the main Puppy filesystem.

The initramfs 'init' script is supposed to find all drives and we have
been able to do it reliably without udev, including reliably finding
all USB drives by our method.

Sometime back I did look into using udev in the initramfs, but it
didn't seem to provide all the information that I need. Anyway, I will
follow your recommendation and take another look at it.

Thanks for the feedback.
