Hello team, Hello Alan, Following up on an Airship-bootstrap call we have had yesterday, Alan described his alternative (lines 92-95 here https://etherpad.openstack.org/p/Airship_bootstrap, search for "isogen uses native go-lang library") which he was talking about close to the end of the call. I remember Alan has described this approach previously on one of design calls, I did not forget about it and I love this solution. What I was thinking about yesterday, was that creating a golang module for the airshipctl would be more complicated (at least for me) than to create a container image for a proof-of-concept stage. I'm all for not having containerd dependency in release version of airshipctl. I'd like to hear your feedback on this. Alan, What was the golang library you were talking about which could open and amend ISO image contents? And another question is what are the standard ISO images (esp. LiveCD) provided by vendors which have built-in cloud-init? Recording: https://attcorp.webex.com/attcorp/lsr.php?RCID=a05f4d1d798f40d79dfda57c9fa0e...
