# INSTRUCTIONS FOR GENERATING THE SPURIOUS LIST
# - empty this list
# - rebuild bootstrap files and update their urls and hashes
# - turn on atime on your FreeBSD nix store filesystem
# - run nix-collect-garbage on FreeBSD to make it so we rebuild FODs
# - build the nixpkgs __bootstrapArchive attribute on FreeBSD
# - reboot your FreeBSD system. Otherwise the atimes will simply be wrong because of kernel caching
# - run a full build of stdenv on FreeBSD. with -j3, this takes 1h40 on my 20 cpu VM (AMD host)
# - use the following to generate a list with access times and filenames
# find /nix/store/###-bootstrap-archive -type f | xargs stat | grep -E 'Access: 2|File:' | paste -d ' ' - - | awk '{ print $4 " " $5 " " $6 " " $2 }' | sort -n > atimes
# - manually identify the point where files have no longer been accessed after the patching phase
# - use your favorite text editor to snip out the time column, the /nix/store/###-bootstrap-archive/ prefix, and the files that have not been used during bootstrap
# - turn off atime if it was off before since it will degrade performance
# - manually remove bin/strings from the list, since it will be used only during bootstrap
# - manually remove all files under include and lib/clang/*/include from the list in order to improve forward compatibility (and since they are very small)
# - plop it here
