I've run into the following issue with parameters that are dependent on
each other. Suppose I have the following class:
class foo(
$owner,
$prefix = /opt/${owner},
$etc_dir = ${prefix}/etc
) {
file{${etc_dir}:
ensure = directory,
owner = $owner,
group =
The evaluation order of the parameters is not deterministic as I learned
when implementing validation of references in Geppetto. (BTW, Geppetto
issues warnings/errors when trying to reference potentially
uninitialized variables as in your example).
You need to move the logic computing the
So will the setting of the values for $owner and $prefix be deterministic,
when set inside a class or resource definition?
Also, what if I want to be able to override these with user settings?
(That's one of the reasons that they are parameters in the first place.)

Yes. The issue with parameters in class declaration is described in
further details here:
