Yes, I’m advocating for using prefix for HEP (at CERN) and HPC in the HSF packaging group, but I think that they are unfortunately more interested in using spack, even though it doesn’t seem to be mature enough for what is its intended use. In any case, since you are from LANL, if your cluster has CVMFS mounted (i.e. /cvmfs/sft.cern.ch), then you can already use prefix! I have prefix installed in CVMFS, which I discussed at CHEP: https://indico.cern.ch/event/587955/contributions/2938043/ Just run /cvmfs/sft.cern.ch/lcg/contrib/gentoo/linux/x86_64/startprefix to get started. In principle, there’s nothing preventing you from using ACCEPT_KEYWORDS=‘x86_64’ in your prefix configuration. It’s just not tried by anyone yet. We all use ~x86_64 for now for prefix on Linux. On Mac OS X there’s no stable keyword, ~*-macos are the only ones.
