I spent an embarrassing number of hours failing to get Talm to bootstrap a cluster because I did not read deeper into the docs that specified you need a separate user volume (due to the zfs extension? it worked fine without it).
Use Talm to bootstrap a Cozystack cluster, for example, should specify in section 4 (Apply Configuration and Bootstrap a Cluster) that you need additional configs for nodes that only have 1 disk available.
Otherwise users end up in a very silent failure mode where talm bootstrap will never successfully bring up the kube-apiserver and so on, for totally unclear reasons.
Talm could also probably check this during talm template? Spit out a warning if an invalid disk configuration is detected, or even automatically create the needed UserVolumeConfig.
