Hi All, As you probably know, it is possible to create a Kata Container using either a rootfs image ("image=") or an initrd image ("initrd=") [1][2]. The former uses systemd to launch the agent whilst the latter uses the agent as the init daemon. Deciding which option is best is up to the user as they both have pros and cons. We are aware of a few changes recently that are making these two options diverge slightly in terms of features (however we do have plans to "pull that back" and minimise the differences). There is also ongoing debate about the use of systemd for the rootfs images. As these topics are related, we've created a wiki page to try to summarise the above including advantages and disadvantages of each approach (image compared with initrd, agent as init and systemd as init): https://github.com/kata-containers/documentation/wiki/Kata-images Please contribute to this page to allow us all to get the best possible picture of use-cases, features, limitations and benefits of each option.
