Hi Ronan, hi Joel,

Doing a *clean* build of Tizen every day/night is certainly a job for a build 
farm like OBS. Other large IVI projects I've dealt with have taken that 
approach. That's not my intention ( though it has the advantage of spotting 
incorrect dependency and build system info ASAP ).

But I've looked more closely now at the Tizen snapshots, and it appears ( 
please correct me if I am wrong ) that they are not clean builds - as far as I 
can see from the dates of the rpms, they are just building the deltas and 
relying on dependencies. Which is what I would be doing, usually.

So yes, in that sense I would just be tracking/duplicating the snapshot 
process, and if all I was concerned about was having current binaries this 
would clearly be a pointless duplication of effort. But what I really want is 
to be sure that I have quick and easy access to the sources for the binaries 
that are actually in my image.

Yes, I could do this retrospectively, and just grab sources for packages on an 
as-needed basis. But if it's easy to always have all the current sources and 
binaries ( and I think it is easy, provided build breaks are infrequent - 
building the daily deltas doesn't normally need a build farm, just a build 
machine sitting quietly in the corner... ), why would I not do this ? What 
risks or disadvantages does this approach have compared to your preferred 
approach ?

Cheers,
Mark
