The reason I moved to FreeBSD like around 2006 was that Linux's virtual memory manager was not very good at that time and whenever you force Linux to swap it usually left the system unstable and required reboot. Whereas FreeBSD you push it to the max (99%+ of swap) and would always recover. And this was way back in FreeBSD 6 and I can only guess it's gotten better, whereas Linux probably is not worrying too much about this since most Linux servers today in AWS don't even have swap, and what for, since they act mostly as a POSIX API on top of multiple layers of virtualized shit. After we made the move, discovering EzJail was the killer feature for us. We were basically doing all the stuff people are doing nowadays with Docker and Terraform etc. We had these kind of flexible and powerful CI/CD pipelines with FreeBSD when these terms weren't even coined as such. That's why I laugh at my younger colleagues who think they are more advanced than what we were doing 14 years ago. And that's the issue with this industry is all the FADs and wheel reinvention. It's the same thing with languages for example. Perl 5 and plain ol C are probably still superior to anything out there today, and only now are we seeing some true advancement in the right direction (e.g. Rust, Go etc.). So if you ask me FreeBSD could probably focus away from this cloud FAD and continue to evolve it's very powerful features and target people that have not gave into this cloud bullshit, and to real sysadmins who are not afraid of taking responsibility instead of hiding behind AWS or Azure. Let them go down that path, and let us focus on reality and bare metal. IMHO, BSD could invest in taking projects like EzJail (plus ZFS) to make this functionality native and EASY, provide an images database and the infrastructure to provide a NATIVE, bare metal equivalent to Docker + Terraform. In other words, FreeBSD and other BSD projects could offer NATIVE and modern CI/CD and IaaS pipelines on bare metal. Just food for thought. Best, -- Alex
