I wanted to reference some scripts under zenpack_install_path/libexec for my monitoring templates.
How to reference the install path as a TALES expression, so I can update zCommandPath to the same.

Say my zenpack install path is as below:
/opt/zenoss/ZenPacks/ZenPacks.org.service/ZenPacks/org/service/libexec/
I have to update zCommandPath as /opt/zenoss/ZenPacks/ZenPacks.org.service/ZenPacks/org/service/libexec/ for the above to work.

But if installation directory were to change, then this will be different.
${here/ZenPackManager/packs/ZenPacks.org.service/libexec} does not work as expected.

What is the correct TALES expression for finding the installation path of zenpack
And how to validate them easier probably through zendmd

Use:
${here/ZenPackManager/packsZenPacks.org.service/path}/libexec/

zendmd test 1:
[i for i in dmd.ZenPackManager.packs() if i.id=='ZenPacks.org.service'][0].path()
'/opt/zenoss/ZenPacks/ZenPacks.org.service-0.0.0-py2.7.egg/ZenPacks/org/service'

zendmd test 2:
dmd.ZenPackManager.packs.findObjectsById('ZenPacks.org.service')[0].path()
'/opt/zenoss/ZenPacks/ZenPacks.org.service-0.0.0-py2.7.egg/ZenPacks/org/service'

Premise: my script/template is part of my zenpack

1.) keep default zCommandPath configuration - you don't need to care about this setting
2.) place your script into /opt/zenoss/ZenPacks/ZenPacks.org.service/ZenPacks/org/service/libexec/myscript.py
3.) set your command datasource in your template - field "Command template":
${here/ZenPackManager/packsZenPacks.org.service/path}/libexec/myscript.py

That's common approach, if you want to include your script/template into zenpack.

Your explanation was very complete and works nicely.
