In this week’s latest release of Fedora Atomic Host, you might notice something
different when you boot the new image. There is now a
Developer Mode entry in
the GRUB boot menu. This blog post will describe why this new feature was added
and what it does.
One of the confusing things that newcomers encounter when they want to try out Atomic Host is setting up cloud-init. Currently, it is impossible to use an Atomic Host image without providing cloud-init with a data source. In the absence of a source, cloud-init will try connecting to various known metadata URLs for about four minutes and then give up.
