Hi Tony,

Since that script (and, perhaps, a c shell version of the same thing) is
in /etc/profile.d/, then all processes source it and get the resulting
environment. The script holds a few values that are useful to a VO's
jobs, usually

gridenv_set         "VO_ZEUS_SW_DIR" "/cvmfs/zeus.desy.de
<http://zeus.desy.de>"
gridenv_set         "VO_ZEUS_DEFAULT_SE" "se2.ppgrid1.rhul.ac.uk
<http://se2.ppgrid1.rhul.ac.uk>"
Etc.

If I remember correctly, the YAIM tool (now out of date) put this file
in place. The site-info.def file had all the values and they got written
in by YAIM, I think. Since YAIM is gone, we have to do it by hand now.

Yes. They possibly came (a long time ago?) from YAIM originally. Or
someone made them by hand...

As far as I know, no package provides this; it is a "victim" of a
decision, quite a while ago, to de-support YAIM. Note: In my view, this
is a grid-wide issue related to the "contract" (i.e. the requirements)
that exists between the Grid and the VOs. We may need to tighten up the
way we deal with these "promises". I'm not sure they are well defined,
anymore, as YAIM played the role of a Standard. Without YAIM, I'm not
sure what the standard is. Hence I'm cc'ing Maarten, to ensure WLCG/EGI
are at least familiar with the issue. It's quite difficult to solve,
since it needs central co-ordination. I'm also cc'ing TB_SUPPORT in the
hope that other UK sites can explain how they manage the problem.

Anyway, since jobs refer to these values, I'm afraid it is your job to
write the file or similar.

Cheers,

Ste
