+1 from me for doing FHS compliance. :)

/var/lib is not actually FHS compliant as it is for "Variable state
information". os-collect-config does have such things, and does use
/var/lib. But os-refresh-config reads executables and os-apply-config
reads templates, neither of which will ever be "variable state
information".

/usr/share would be the right place, as it is "Architecture independent
data". I suppose if somebody wants to compile a C program as an o-r-c
script we could rethink that, but I'd just suggest they drop it in a bin
dir and exec it from a one line shell script in the /usr/share.

So anyway, I suggest:

/usr/share/os-apply-config/templates
/usr/share/os-refresh-config/scripts

With the usual hierarchy underneath.

We'll need to continue to support the non-FHS paths for at least a few
releases as well.
