Looking at the notes on fedoraforum it seems we have a slightly different
approach. He's gone for space saving by switching to busybox. Our goal
was that we wanted to keep the same pieces of functionality, just strip
out the bits we didn't need, so we don't have to spend time debugging
differences between busybox & coreutils. Of course finding the bits 
which aren't needed is fun in itself & somewhat of a moving target. So
whereever possible we've been filing BZ to get som5Ce RPMs split up into 
finer grained sub-RPMs
