sure? I think that changes nothing, because sarge users will normaly have 
hotplug and udev installed. even if you at say: "I depend on udev >= version 
xyz OR hotplug" the dependency is satisfied, because hotplug is installed and 
that is enough. it's a OR dependcy, no matter if you first mention udev or 
hotplug...

or is it really handled diffrently in debians dependency system?

it is... as I said, hotplug works on every debian release... hotplug is not 
the problem... udev is a bit more complicated, because for some versions it 
coexists with hotplug (but then it's to old for xen) or in more recent 
releses udev even provides hotplug.

(btw. all my production systems at work are actually debian sarge boxes with 
just hotplug installed).

ack! I think more systems will be running sarge + xen then etch/testing + xen 
for a long while...

I don't believe that the next release is really in december. i would even bet 
on that :)

I would like that your solution is working, but I thinK there is no real 
difference between:

"hotplug | udev (>= 0.059)" (what I used till now)
and
"udev (>= 0.0XY) | hotplug" (what you suggested)

(where XY is the first udev version that provides hotplug).
