IMHO: We are making a great progress folks. Thanks to everyone who is
testing or on the way to test the RAC Attack instruction. This is a great
community effort.
Just a few thinking loud comments from my side:
-- We should pay attention to any comments and think how to improve the
instruction (Ludovico does the good job on responding to the questions). If
some people doesn't notice or miss steps there is a good chance that they
are not going to be alone. We need to think how to make the steps more
visible (may be even adding comments and references in some other parts of
the manual stating "pay attention to XXX some people may miss it")
-- Correct me if I am wrong but it looks like the main part of the
instruction is platform generic now. There is no difference if you
implementing it on Mac or Windows (may be just a very few things like,
shared dir setup and possibly routing). Everything else including
resolve.conf happening within the VMs and are generic to all platforms.
OOW: As suggested by Ludovico we will need to organize ~1h RAC Attack
Ninjas' briefing to discuss the way we run the event (possible presenter -
Yury, may be someone else) and go through most important (where people have
most of the confusion) steps (Presenter ?Ludovico?). Let's try to find a
good time for the briefing. I currently thinking Monday morning/evening.
Monday Morning may be better as we could check the RAC Attack space onsite.
