Conservative settings were used to minimize false-positives but there's still a chance that the above list contains non-issues. Running shellcheck again with default settings could detect other possible issues. References: [1] this script: https://github.com/heeplr/gentoo-shellbug [2] shellcheck: https://www.shellcheck.net/
