Re: Making Fedora Core CD #1 Standalone -- Now you're seeing it my way!



[ I think at this point I've spewed enough vapor, so it's time for me to
go off and do something.  I really appreciate *EVERYONE'S*! input on
this.  I'm going to try to have a "nailed down" comps.xml by the
weekend, and identify some of the "BS dependencies" that should be
removed (if any) on various, basic packages. ]

I think some people are missing the fact that I _do_ recognize that. 
And that's why I'm advocating that the full "Core" _not_ be touched.

This new sub-Core would be explicit.  Ideally it would be Core CD #1.

Right.  I don't disagree with that.

I think that was what I was saying.
But maybe I wasn't saying it as clearly?
My apologies ;-).

Now you're seeing it my way!
Thank you for re-iterating it in another way.
Maybe now others will see it as you do.

Right, and I'm going to start play with it.

Well, I'm anal.  I'm thinking of the company that has its own, internal
Apt repository.  So it's easy to fetch what you need for different
systems.  Eventually the company should write its own comps.xml, but
this "Quark" gives them a "nice base."

Eventually I'd like to see the "Quark" weed out a lot of stupid,
unnecesary dependencies in "Core."  But that's a future ideal.

I'd go the other way.  No apps.  Why?  Because in short order, it will
bloat to more than 1 CD.  The idea here is to make it as small as
possible.  Even if its only 300MB or smaller.

Someone can _always_ "fill" the official "Core" CD #1 with more -- but
it all starts with the "Quark" comps.xml _first_, as the "base."  We
need more than the 90MB one (although that's not a bad start).

BTW, does that list include Kerberos?  I probably need to find out by
using RPM-Analyzer.

I  see little reason to include development.  They can be fetched via Apt/Yam.
For those that can't, Quark is not for them.  They should install the full
"Core" instead (possibly from 3rd party DVD with Extras added).

But at what point do you start not including stuff?  I say devel is out
for "Quark."  You have Apt/Yam to fetch them anytime you need.

Here's what I think should be in "Quark" (or whatever it is called):

- Everything in "Minimal Install" (90MB)
This is a suppport consideration

- All client network services for basic X/GNOME functionality
- All client probing/hardware support
Everything from DHCP to Mozilla, and the GTK+/GNOME to run it
This includes Fonts (which can quickly be a size issue)

- All directory service, authentication, crypto clients/services
- All network client/services having to do with file
Because if you can't connect to any network setup, you can't fetch

And that's all.  No extra GNOME applets or goodies.  No bitmaps other
than maybe the Fedora one.  No frills.  Those can be apt-get'ted.

In an enterprise environment, I'd rather have a "base" install like
Quark on a CD, and then run a script that does an "apt-get" of
everything else needed.  But that's just me.
