Re: [vdsm] [Engine-devel] RES: oVirt 3.4 test day - PPC support

Yes, sounds like the overriding of vdsm.conf is an issue that we need to avoid
what I wonder is that it is not a regression, old versions of vdsm also overwrited the vdsm.conf file during deploy, so how is it harming us only now?

please open a bug on the overwriting issue

Thanks.
