Updating W2KPro SP2 system with SP4 & Rollup 1 - what to do with the previously installed patches?

[tanstafl]

W2K SP2 w/about a dozen pre-SP3 WinUpdate applied fixes, Security
Rollup 1 from Jan 2004, and the recent WMF patch from Ilfak.

I've read through all the material I could find on the usoft site
about SP4, but there was no explicit mention of whether I should
manually remove the existing patches listed in add/remove programs
prior to installing SP4. I assume by the lack of removal instructions
that SP4 will housekeep and delete the patches, but I've never
installed an SP atop existing patches. Can someone please confirm? I
do plan to remove Ilfak's WMF patch. just prior to SP4.

To answer my own question, SP4 deleted all the WinUpdate patches in
add/remove except one (a post-SP4 patch) - and Rollup 1 nailed that.
So I guess the generic answer is that an SPx or Rollup package will
housekeep on patches that are included within that distribution
package.
