A great advantage no doubt.=20

Is it really better than iptables? I just don't know iptables therefore
am asking. But there is a number of things I'm unhappy about pf.

How is it used in the real world?

I think we can find similar things in the Linux world. But the
separation of the base system and third-party software from
ports/packages is a great advantage, I think.

and netgraph. These are powerful technologies, no doubt, but they are
rather tools for FreeBSD developers than something visible to
"outsiders" and general users/admins.

rctl could be important, but Linux has cgroups, they are probably
basically the same.

 From the point of view of maintainance ans aesthetics, I agree FreeBSD
looks simpler and cleaner (unless you're trying to use the GUI). I have
chosen a workflow similar to yours (ZFS, custom poudriere repository)
but bhyve VMs instead of jails. Thanks to ansible, creating and updating
those VMs is not very boring. Disk space is cheap nowadays, so I don't
becry the overhead of keeping a complete base system in each VM.

Well, the advantage of Docker is probably its wide community acceptance
and popularity. I think a similar product could have been easily created
with FreeBSD jails, mount_union, VNET etc but nobody took the trouble of
creating it in the first place. You need a repository with popular apps
packaged as jails (base system, nginx, mysql, postgres, php of different
versions, exim, drupal...) then this product could become a success (if
not too late).
