@metanovii thanks for opening an issue! All keys are internally converted to a unified form by confd, so even if the key doesn't have a / as a prefix it will, in fact, have a / as a prefix after it was fetched by confd. Therefore, you can reference the key someprefix/somekey as a /someprefix/somekey in confd.

I try

{{getv "/someprefix/somekey"}}

and

{{getv "/someprefix/somekey"}}

and get

confd[10956]: ERROR template: list_domains.tmpl:1:2: executing "list_domains.tmpl" at <getv "/someprefix/so...>: error calling getv: key does not exist: /someprefix/somekey
