Wow, this is why I use Sashimi/Makisu... it does all this in WAY easier steps, and it supports ALL UC/SDConfig.txt options.
Over at XDA there are many "former" UC fans that have moved over to S&M (I kinda like that acronym) so I'm not alone. It's as easy as RTFM and tutorial videos.
Other nice this about S&M is it allows you to "test" a clean ROM for a few days before you run all the customization.
I'm not knockin' UC: Sleuth put a whole heck of a lot of hard work in developing it, but S&M just takes this ball of wax to another level.
