Ah, thanks for explaining.  So, we call this script "febootstrap-minimize" not because we actually use febootstrap (we used to, but abandoned the script on account of febootstrap being deprecated), but because it turned out that what febootstrap-minimize was doing was useful and not terribly harmful.

So to answer your specific concerns, I don't personally see any issue with a stray `rm -rf` that doesn't delete anything (/var/cache/yum) or with adding the extra cracklib stuff for rinse which may or may not benefit from it (but certainly shouldn't be terribly hurt by it).

Does that sound reasonable?
