Subject Re: configdrive in ACS
Date Mon, 12 Sep 2016 11:38:34 GMT
Hi,
and thanks for answering.

Yeah, I've read the docs and I've seen the cloudstack cloud-init
implementation in ubuntu cloud-image

So since configdrive is not supported I think I need to follow your
advice and rather make a script fetching needed information from
cloudstack instead and then start services needed in shell.

thx,

hw
