Hi Thomas

thanks for chiming on the subject. Since you're the MrFaI I am not
surprised to see a FAI based solution :) I had a look at tap devices
assignment and it works well.

For the record
https://www.kernel.org/doc/Documentation/networking/tuntap.txt
has the bit about the permissions and the security implications

as long as I can reproduce the build outside casulana (that was my main
grief with petterson-live) so we can build for Vagrant boxes a CI
toolchain, on top of that I am fine with every technical solution here.
