in the cvmfsfermilab tools, I'm adding:
- bin/spack-cvmfs which lets you run the commands below, which function by adding entries to /grid/fermiapp/cvmfsfermilab/triggers/$which/workfile for the update_spack script in the spack_infrastructure product (which only does buildcache installs, btw)
- spack-cvmfs which install "spec"
- spack-cvmfs which uninstall "spec"
The workfile can also have untar entries, but those must be hand added.
