Comment 16 for bug 1732703

I would accept a version of this SRU that hard-codes the choice of upstart as the init system on 14.04, because that is the only init system supported in that version of Ubuntu.

We can discuss further whether the deput-init systemd package in trusty needs further changes to not fall afoul of common init system detection techniques, but I don't think that should block fixing MAAS in this scenario.

Currently, all the proposed methods of detecting the init system have corner cases where they break. Most of these corner cases are negligible for maas, however.

The one option I know that doesn't have corner cases is to invoke '/sbin/initctl version' and check its return code. But I leave it up to the MAAS team whether to implement this vs. a lighter-weight check.
