looks like i misread the behavior here.  ldconfig does only access/write to 
things inside of the -r ROOT.  what threw me off was that if you run this as 
non-root, ldconfig uses full paths everywhere (ROOT/etc/...).  but if you run 
it as root, it first does chroot(ROOT), then uses absolute paths after that 
(/etc...).  so if you miss that initial chroot(), it looks like ldconfig is 
crapping all over places it shouldn't.  so i guess i'll drop this patch from 
consideration.
