Funny you should mention that....  I think some folks have no idea what they
are talking about when they use the word "bloat".  At least they don't
define what they are calling "bloat".

For fun...and since it was raining here part of the day....

I did a default "all" install of the current stable slackware and an "all"
install of the latest F8-beta on the exact same hardware.  I then started
them both in run level 3.

As soon as the systems were up I checked top and lsmod.  Now, this wasn't
entirely one-to-one since on my F8 install I did use LVM while I didn't on
the slackware.  Also, slackware is at 2.6.21.5 while F8 is 2.6.23.0.

That should advantage Slack.


F8 loaded a total of 60 modules
Slackware loaded     38 modules

The /lib/modules of F8 was 57MB while slackware is 52MB.

Now, the really interesting thing was that top showed F8 to be using 147.9MB
out of 512MB while slackware was consuming 179.4MB.

I find that interesting.....

You should also include the kernel size. I was amazed when i first used debian to find the bare kernel didn't support my IDE hardware: the IDE drivers were modules.

If you still have both, find how many modules each has under /lib/modules. And, if you still haven't got a life, see if you can pick the differences: one might, for example, have madwifi even though the HAL is binary-only.

Part of the requirement of any commercial distro is that it must support all likely hardware. That's constrained, in part, by attitudes to lack of source: Debian hacks stuff out of the kernel because some is not DFSG-free.
