I'm seriously skeptical of this protocol performance. Ethernet and TCP/IP induce a pretty heavy overhead. This overhead is totally acceptable in LAN/WAN networks, but in case of storage network you want to keep latencies as low as possible.
> OSTree only supports recording and deploying complete (bootable) filesystem trees. It has no built-in knowledge of how a given filesystem tree was generated or the origin of individual files, or dependencies, descriptions of individual components.
Um-m, isn't this what snapshots (e.g. LVM snapshots) are for? Correct me if I'm wrong.
I use SaltStack for managing a render farm consisting of 73 Ubuntu nodes. My requirements are rather simple, really: most states just install some packages, put configuration files into place (sometimes using a template) and enable/start services. However, I can't recall a single problem when setting everything up. SaltStack is clean, simple, and just works.
