Hello Jamie,
Thanks for the clarification, I didn't realize that install_novnc.sh being
in two different locations was a bug.
I hadn't installed OpenNebula on anything other than a Debian / Ubuntu
system, so this makes sense.
is there any userspace documentation we can contribute to? Even if not the
documentation itself, perhaps a wiki? I didn't see one but that doesn't
mean there isn't one.
Thanks,
Jon A
