Subject: Re: [Oscar-devel] SOC(oscarlive) The Test LiveCD with the GNOME DEis ready!!!
Hi Ravindra,
as far as I understand, the live-cd
currently doesn't contain OSCAR, right?
Do you think you'll be able to fit
OSCAR and an image to the liveCD?
What concept will you use for the
client nodes? Will they use a special
OSCAR-Client-LiveCD? As opposed to the
OSCAR-Master-LiveCD? In that case
Client's won't need to be
installed.
Or will the LiveCD provide the client installation image? In
that case I guess
you should rather think of a liveDVD... For that case, you
might want to have
a look at the vmware OSCAR appliance at
http://www.vmware.com/vmtn/appliances/directory/341
This
case is for really installing the client nodes (and erasing their
disks!!!).
This can make sense if somebody wants to quickly test a
cluster
software.
In any case, you need a liveCD for the Master Node
which won't try creating a
client image in the master's
RAM-disk.
Regarding the used distro, I don't really care and believe that
you should
not care too much, either. LiveCDs are usually for quickly trying
out some
features of the software, and OSCAR should have the same features on
every
distro.
Best regards,
Erich
