I've also started to produce a minimal.iso (and so packages manifest)
It's not about the packages size, but the size of the install media
*without* any package at all (and metadata) :

5.9M		EFI/
438M	images/ (we can remove boot.iso , obviously -> 76M)
70M		isolinux/
279M	LiveOS/

and we still have to add the packages .. so not sure it will fit on a
single CD. and if the goal is to produce a DVD iso image, I don't think
people will be interested in "wasting" a DVD for a ~1G iso instead of
the normal DVD, that covers both minimal and other "variants" ...

I'll give it a try though (and speaking about minimal, not micro
instance that was mentioned too)
