# Test resource settings for the locally rebuilt x86-64-v3 package set.
#
# Selecting x86-64-v3 changes every affected derivation, so the normal
# nixpkgs binary cache cannot be used and upstream test suites run locally.
# The jeeves builder uses /tmp/nix-builds so filesystem tests run on tmpfs
# instead of ZFS with normalization=formD and utf8only=on; those tests remain
# enabled. This overlay no longer excludes any tests. The remaining settings
# bound nested worker concurrency and allow time for worker startup under load.
# Test repairs and their validation are indexed in patches/README.md.
