Re: [NEWS] status of boot-flopppies
Moin Massimo Dal Zotto,
Our CD started that we installed a debian system and asked it for
selection. We put those files on a single CD (420MB) so our distribution
is self consitent, even if its only a small selection of Potatos.
We have tested this selection of Potatos to be usefull for initial
installation, and we'll next test it to be usefull to upgrade older
debian systems.

If we now want to send an update CD, that may contain lets say mozilla.m11.
I should provide any libs and depencicies on that mozilla.m11 needs also on
this update CD. So if somebody wants to update from mozilla.m9 (on our
current CD) to mozilla.m11, he does not need anything but my update CD.
Peter Ganten (peter@ganten.de) had written our script to walk the
dpkg/status and collect any dependencies.
Its imho quite easy for a single debian update CD to focus on a hand
full of topics and to provide a consiten update for those topics. Any
update CD should also contain a minimal complete update of basic
packages. So there is no need to change debian to provide smoth update
CDs, and its even impossible to provide smoth update CDs that asumes
a changed Debian, as the change would perhaps become implemented after
the initial system was installed.

this is fine for a multi CD installation, if you asume that somebody
wants anything. Lets say somebody only wants one platform (e.g. i386 :-)
so he'll have around 3 CDs, if no package is on more than one CD or
4 CDs, if any CD is self consistent. For the first installation the
3 CD version (like standard debian) certainly has advantage, but on
the long run self consistend CDs are easier to handle, imho.
Bye Michael
