Description Chitlesh GOORAH 2006-07-03 19:54:25 UTC 
Description of problem:
This is a RFE with respect to Kadischi.
It would be nice to have anaconda calculate the expected size of iso image
during package selection (when run in --livecd mode)
The size of the iso image will be based on mksquashfs
 - to be able to parse a factor to do the calculation with respect to the actual
size of the selected packages.

Version-Release number of selected component (if applicable):

The size can't be done during package selection -- dep resolution on the fly
would make it *way* too slow to be viable.
Comment 2 Jasper O. Hartline 2006-07-06 03:45:47 UTC 
I agree, I think this is Kadischi's job for now. 
Right now observed SquashFS compression comes out to between 2.5 and 2.7 times
smaller than the original builddir's rootfs.

So what we've done is simply query the rootfs RPMdb headers for the SIZE and add
them up, divide by 2.5 and print how many bytes estimated it would be. This
actually works and works well for this task. The querying is done immediately
after Anaconda exits.
