[one-users] problem with RANGED network (or caching)

[Carlos Martín Sánchez]

Hi Rolandas,

I'd say that your better option is to move those commands to the init.sh
script. Just put in the CONTEXT all the variables you may need, I'm
guessing that would be $NIC[IP,NETWORK=\"NET-NAME\"]. These variables will
be written by OpenNebula in the context.sh file, which you can "source"
from init.sh

More information in [1].
