I've just switched my firewall machine from RedHat 5.2 to Mandrake 8.2 with 
SNF.  As part of my testing and to minimize firewall downtime, I did the 
installation and configuration on one machine and then moved the hard drive 
to the firewall machine.  During this process I watched the system boot 
multiple times and noticed a couple of slow spots.

First was kudzu.  The hardware detection takes multiple seconds, i.e. 
there's a very noticeable delay.  Seems to me that kudzu should be enabled 
when changing hardware and disabled otherwise.  (In my case it was very 
useful as the configuration machine has a PS/2 mouse and the firewall 
machine had a serial mouse.)

Second was ipvsadm.  The boot process _usually_ takes a minute or so for 
"Applying ipvsadm rules from /etc/iptoip.xml".  I haven't investigated this 
one.

Third is generating modules.dep.  The Mandrake kernels all have LOTS of 
modules. This generation process is _slow_ (on the Pentium 133).  Using a 
custom kernel with many fewer modules, generating the file is much faster.

I don't know if this information helps or not, but it's what I've noticed.
