No, because live upgrade can't run programs from the newly installed root; it can only run bits from the current root. Also, we support older live upgrades and currently have no bash in the miniroot also (for install/upgrade). Because of live upgrade, you can only use non-optional feature which existed two releases ago, unless you postpone running the scripts to first boot. Casper
