Hi all,

thanks for your replies

I would like to avoid suggesting users to extend their fpath themselves:
the entire idea of that script we're deploying is there is exactly one
place to pick a version of the software stack, so users do not need to edit
their shell setup, log out&in to switch versions, which we want to enable
them to do after logging in. also our homedirs are shared over different
operating systems …

I appreciate the comment that my idea would hammer zcompdump, I'll try in
any case what the time penalty on our systems is.

Anyway the snippet by Sebastian looks good and seems to do the job.
(And I don't need to worry about users who might call `compinit -u`)

Thanks,
Paul
