alt Hacker NewsI don't think it's necessarily true, compare the BSD utils to the GNU utils and the style difference is very visible.
On the other hand, I don't think the comparison between jails and docker is fair. What made Docker popular is the reusability of the containers, certainty not the sandboxing which in the early days was very leaky.

Well, what style difference exactly? GNU utils tend to be more verbose. Other than that, what is the difference in style?

Indeed, that Docker is functionally a cross-distro rolling release package manager, configuration standard, and service supervisor[1] is the appeal to me. Any isolation it achieves is necessary for that to all work reliably, but is not why I use it.
Inability to find a service I want to run on Github and 95+% of the time to be able to configure it and have it running and fully managed with usually just a one-liner shell script like 10 minutes later just by finding an existing docker image is the thing I’d lose with jails. That’s all of the value of docker to me personally. Jails could be a building block toward that, but last I checked there’s no deep and up-to-date library of “packages” I can reach for, using jails, which makes it pretty much useless to me.
1: I have like eight or nine services running on my home Debian system, they all auto-restart and come back up on reboot, and I’ve not had to touch Systemd once on that machine.
