I manage my modulepaths via puppet recipes. When they change, puppet sees it, but Foreman doesn't until I restart it.

As discussed with Ohad (on IRC) :

<marcellods> btw, is it normal that I have to restart foreman when a modulepath (from a puppet environment) changes  ?
< ohadlevy> marcellods: yeah, foreman reads puppet config upon initialization
< ohadlevy> marcellods: unless you run it via rake
< ohadlevy> it would take longer, but we can check if the modulepath changed
(...)
< ohadlevy> marcellods: ... i think that the rake task should detect it
< ohadlevy> marcellods: it should not detect it when you click on import from the ui
