* Add improved handling for TLS certificates for static builds. * Properly replace symlinks. * Fix shellcheck warning. * Fix option handling. - Persist certificate handling mode and check URL across reinstalls. - Properly consume the arguments for the certificate handling options. * Add five minute hard timeout on certificate check. * Differentiate specific error results from curl. * Persist cert handling options regardless of how they’re passed in. * Escape slashes in REINSTALL_OPTIONS. * Fix escaping of reinstall options.
