drmaa chown sudo

Matthias Bernt
Dear galaxy-dev list,

The documentation
(https://galaxyproject.org/admin/config/performance/cluster/) mentions
that sudo permissions for /usr/bin/chown are required in order to run
jobs as a real user. This causes quite some headache to our system
admins (understandably).

I tried (unsuccessfully) to dig a bit in the sources to find the
place(s) where sudo chown is called (the idea was to create a small
wrapper which might get sudo permissions).

But I found that there is already scripts/external_chown_script.py
(which is also referred in galaxy.ini). Is it sufficient to make this
script sudo callable? Or where could I invoke a wrapper for sudo chown
in the galaxy code?

Thanks a lot.

Best regards,


Matthias Bernt
