moreover on libudev

looking at Debian bug 735275
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=735275

and the wide impact it has on upstream (nodejs, webkit, chrome etc. are
affected by the bump to libudev.1) I'd rather keep libudev.0 around as
a vdev patched version, would that be possible?

I understand this would gain Devuan even more backward compatibility
with upstream distributed binaries.
