&gt;&gt;<i> BTW, I once calculated (test plus extrapolation) how long it would take
</I>&gt;&gt;<i> to rebuild every package in Mandriva on a low end 2 GHz Celeron server
</I>&gt;&gt;<i> that I had available and it came to about 80 days.
</I>
With a reasonably good machine, we used to be able to rebuild most of
&quot;main&quot; in about one day.

&gt;<i> Perhaps I was naive in thinking that compiling the distro could be
</I>&gt;<i> done with distcc or even a simple queuing system that distributes
</I>&gt;<i> SRPMs to nodes in the community swarm.  As each node returns its
</I>&gt;<i> completed binary package, the queuing system could send it another
</I>&gt;<i> SRPM to build.
</I>&gt;<i>
</I>&gt;<i> It would be cool if it could be done that way.  Why pay for data
</I>&gt;<i> center space, hardware, electricity and big bandwidth when you could
</I>&gt;<i> have a community-provided &quot;cloud&quot; for free? :o)
</I>
Because there are some authentication and integrity issues which are not
simple to solve: we have to be sure that the binary packages really come
from the unmodified SRPM (so that it does not contains malware).
