su setuid lost after upgrade
After an Alpine upgrade, eg: apk update ; apk upgrade su is upgraded to a link to the busybox binary without setuid.
This causes the obvious error: 'must be suid to work properly' but also it causes the sudo rm -f $SCRIPT_PATH call from zzzzzzzzzzzzzzzz.sh to hang the system. That seems to be due to too much indirection. Prior to the upgrade it was script->sudo->su and after; script->sudo->sulink->busybox su noting script->sulink->busybox su does not hang the system.
