Windows XP Service Pack 2 Slipstreaming Tricks

[Ascii2]

I have noticed that on the webpage referenced by the following link ("My host OS is Windows 2000 — Slipstreaming SP3 fails" section), a trick is stated to allow slipstreaming of Windows XP Service Pack 2 into a Windows XP with Service Pack 2 installation source:

Where can more information about tricks to allow Windows XP Service Pack 2 slipstreaming form Windows 2000 be found?

Also in the "My host OS is Windows 2000 — Slipstreaming SP3 fails" section of http://hfslip.org/xpsp3.html , using a "custom update.exe" is mentioned for the slipstreaming of Windows 2000 Service Pack 4 into Windows 2000 Datacenter Edition.

What benefit can be provided by using update.exe from update packages other than from the original update packages?

Which update.exe programs can replace a package's original update.exe?
