A couple of things I noticed:

This can be coreutils-minimal

These can be (search-input-file #$inputs "/bin/grep") to make it easier
to swap out the packages for something else if people want.

I checked the script, it should be ((" sed ") since there are a couple
of instances of 'sed' in the script which aren't invocations of sed.

Are there more binaries which should be substituted? I saw glxgears,
chcon, a couple instances of java, pwd, valgrind, docbook paths. And
then there's a couple of other scripts and binaries in the bin/ folder.
I think it'd be better to use wrap-script or wrap-program and then use
substitute* to strip the leading /usr/bin/ from the different calls to
the different binaries.
