 Our initramfs uses busybox-1.15.1 and occasionally has the task of purging
 old /versions trees using "rm -rf".

 Busybox's "rm -rf" is quite a bit slower than coreutils version. Tested on
 a running system, timing the deletion of a hard link tree made as follows:

 {{{
 cd /versions
 cp -l -a * delete_me
 }}}

 9 seconds for busybox vs 6 seconds for coreutils. (busybox seems to be
 even slower from the initramfs, not sure why)

 Opportunity for speedup here.
