# since this bit is cross-platform:
# - first try with `command -vp` to try and find
# chown in the usual places
# * to work around some sort of deficiency in
# `command -p` in macOS bash 3.2, we also add
# PATH="$(getconf PATH 2>/dev/null)". As long as
# getconf is found, this should set a sane PATH
# which `command -p` in bash 3.2 appears to use.
# A bash with a properly-working `command -p`
# should ignore this hard-set PATH in favor of
# whatever it obtains internally. See
# github.com/NixOS/nix/issues/5768
# - fall back on `command -v` which would find
# any chown on path
# if we don't find one, the command is already
# hiding behind || true, and the general state
# should be one the user can repair once they
# figure out where chown is...

I wanted to take root ownership of existing Nix store files,

To manually change file ownership, you can run:
sudo chown -R 'root:$NIX_BUILD_GROUP_NAME' '$NIX_ROOT'
