Code review comment for lp:~savoirfairelinux-openerp/lp-community-utils/pep394

If I understand correctly, we are trading a small smoothness advantage for old distributions vs. more up-to-date ones that received pep394.

I lean a bit for calling python2 explicitly. I prefer those with old distributions to go through some (easy) hoops to comply with future-proof pep's that the contrary.

In any case, these scripts are used by people that can figure out how to work around the problem in both cases, so I won't fight over this.
