This thread would not be so long if docker/containers solved the problems, but it did not. It solved some, but introduced new ones. So we cannot really say its better now.
The only thing I can deduct from this thread, is the necessity to create a solution for eg. 'dentists' to install a ceph cluster. Everything really related to container use is moved to the future. The focus of the cephadm development more or less shows this.
Again, I think focus should more on a working ceph with clean documentation while leaving software management, packages to admins. And staticilly linked binaries would certinly solve dependecy hell and "how to support other environments" for most of the cases.
I agree, and I worry that at some point only docker images are going to be available, and/or a CO environment that I do not want.
