pungi & nrofdiscs?

[Jeroen Janssen]

Hi,

I just was wondering about the discs option in pungi.

Wouldn't it make more sense to just specify the size of disc(s)?

I mean, specifying the nr of discs implies that you know beforehand
the total discsize needed. What if I specify discs=5 and somehow the
needed discspace exceeds 5 discs?

If we just could specify the size of the discs, that means you
automaticly end up with the amount of CDs needed for everything you
want.

Anyway, this way if you want to generate a DVD you just specify
discsize to be of a DVD, or if you want multiple DVDs (think about
CORE + EXTRAS) that's also solved aswell then.

The only 'downside' is that you probably need multiple runs of pungi
if you want to generate both DVD and CDs.

Any other thoughts on this?

Best regards,

Jeroen Janssen

The problem is that anaconda-runtime is what splits the content across the 
CDs.  It doesn't have the ability to look at the size and divide evenly.

The roadmap is to move the splitting and package order logic out of 
anaconda-runtime and into createrepo itself, so that createrepo can split 
evenly across, splittree would just follow the manifest laid out by 
createrepo to put the packages in the right place.

Neither of these things fall under the pungi project, pungi just makes use of 
these tools to get the compose created.
