     Daniel, my point was just practical, although it's obviously 
Aitor's buzyness.


     Jude organized his install process so as to put the files under 
/usr/local, so that testers could easily test it without interferring 
with the hotplugger in function. As such, the package does not need to 
exclude Udev.  I tested Vdev with the normal file hierarchy, in a tiny 
OS Busybox-based, and I didn't read any report of anyone else having 
done so.


     Several months ago, when I stopped testing Vdev in this way, it was 
working fine. But the latest version isn't working properly and I don't 
know the reason. I cannot exclude that the reason is in handling the 
file hierarchy. Vdev manages a lot of files, much more than Udev. OTOH I 
didn't read any report of a successful test of this latest version under 
/usr/local.


     This is why I suggested to go step by step and not build blindly a 
final version of the package which would force the removal of Udev and 
replace it with something which doesn't work. But,
again, this was just a friendly suggestion to Aitor, who probably 
doesn't need it. And this suggestion caused a useless discussion which 
is why I regret to have made it.
