Definitely too large.. but not by a lot.

The informal Critical Path for current QA testing is: yum and its deps.

No matter how bad *other* things are broken, as long as yum works you
can 'yum update' and download fixes. But if yum breaks, you have a
Severity CFF issue [1].

Note that by "yum and its deps" I don't mean the actual "Requires:" on
the 'yum' package, I mean "everything required to have yum run
properly". So this includes stuff like - duh - networking. 

So, throw in NetworkManager and its deps. Like it or not, NetworkManager
is the default network management system, and if it doesn't work, we are
once again registering Severity CFF issues.

Since this discussion is about defining a *formal* critical path, I
propose the following:

Bootloader: grub (yaboot on ppc), kernel, and all dependent packages.
Networking: NetworkManager and all dependent packages.
Update system: yum and all dependent packages.

I *believe* that would pull in everything Patrice mentioned earlier
(e.g. kernel requires initscripts, mkinitrd, module-init-tools, etc.
mkinitrd requires lvm, e2fsprogs, bash, coreutils, etc.) and all those
things that are completely vital that sometimes we don't think about
(dbus, cough cough cough).

This will define our Tier-1 / Core / Critical Path / NTBFW[2] package
set, which should have some additional sanity checks / scrutiny applied
during updates, release testing, and so on.

[1] Completely Fucking Fucked. A common QA term that I just now made up.
[2] Not To Be Fucked With. More QA parlance that I just now made up.[3]
[3] Us QA guys have dirty mouths. Or, at least, I do.[4]
[4] Oh come on. Show me a QA engineer who has *not* shouted curses so
vile as to cause scarring and/or spontaneous combustion in lab animals,
and I will show you a ticking time bomb of rage. Or a mute. Or someone
who is no fun at parties.
