Gosh, I see what you mean. It bloats up the CD quite badly and still takes some time on the 13min mark because of all the downloaded hotfix files its executing. And even when it does that, I can't see any point copying the extracted files into the i386 folder since the hotfix files itself is going to be doing that via [setupHotfixesToRun] so people might as well remove their defined cat files in the svcpack.inf file. I've also tested a hotfix slipstream a month back, removing all the entries from [setupHotfixesToRun] and leaving the cat entries there. (thus, removing the bloat) It slipstreams and doesn't halt at 13mins but the registry entries are not imported causing Windows Update to report incorrect information. Royalbox and Greenmachine might have possibly found a way round since, but I decided not to go any further as it started to get somewhat complicated
