If you want to really strip down an install, removing cpio is a good candidate since it duplicates what's in tar, and tar is more popular - especially for interactive use. > Which implementations of cp don't implement -R and -l? > > > Probably most of them, except GNU and newer BSD.

Also, I think GNU cpio is a reimplementation, not the original. cpio's been around since PWB/Unix, which sits between 6th Edition Unix and 7th Edition. It should be in just about everything, unless a vendor/distributor got pretty zealous about cutting duplicate utilities.
