Compute Canada

(via Bart Oldeman in EESSI Slack on Tue June 2nd 2020)

• general notes: https://docs.google.com/document/d/1F1WAsHJrfr_SnK09OyZG6oifAanHiQdkpJZ24N0GytM
• modified bootstrap script: https://github.com/ComputeCanada/gentoo-overlay/blob/master/scripts/bootstrap-prefix-stable-nixpkgs.sh
  • some of this is only required to bootstrap from Nix environment

First thing to try:

wget https://gitweb.gentoo.org/repo/proj/prefix.git/plain/scripts/bootstrap-prefix.sh
chmod +x bootstrap-prefix.sh
EPREFIX=/cvmfs/soft.computecanada.ca/gentoo/2020 ./bootstrap-prefix.sh

This makes it stable:

This is another tweak you may need and adjust (add all languages spoken in your countries):

Last but not least there was a bug in the bootstrap with gawk, which may have been resolved since then:
