Since Dehydrated only has a single HOOK parameter you can use this script to dispatch the hooks to multiple hook-scripts.
New insights show this script is completely unneccesary and is only still here for historical reasons. It does work but using this method is much easier.
Nothing special, only tested in Bash.
Set dehydrated-dispatch-hook.sh as your HOOK script in Dehydrated and create a configuration
file as /etc/dehydrated/dispatch-hooks.inc. It should look like the following:
HOOKS=(
"/opt/dehydrated-hook/hook1.sh"
"/opt/dehydrated-hook/hook2.sh"
)The hooks will run in the specified order.
