So can anyone give me a short explanation on why someone would use freeBSD over linux? I do run it technically, on my router (OPNSense), but that's not a personal computer, like a desktop or laptop. What are the advantages to running FreeBSD?
For developers, it is interesting to think of as a self contained toolkit. If you are building firmware, platform images for bare metal or cloud, it creates a much better demarcation than any attempts Linux can put forth. This is related to why you might like OPNSense. But if you are just a consumer it only indirectly matters to you.. consistency of build and product, quality of subset of network drivers and subsystems like pf to support your mission, ability go in and quickly and correctly fix the right problem at the right level etc.
1. I subjectively just like it better. Things like dtrace, jails, the init system, just click for me.
2. I think it's good to not support a Linux mono-culture. Yes, there is Windows and macOS, but in terms of open source OS's, I think it's good to have more than one choice and so for any rough edges in FreeBSD, I'm willing to deal with them to support that goal.
3. I don't think you'll find any actual, hard, technical reason to want to prefer FreeBSD over Linux on a desktop. Anything you can do in FreeBSD you can do in Linux. Heck, FreeBSD is probably even running the Linux version (for example video drivers).
But really, which Linux do you mean? Nix? Gentoo? Red Hat?
But the comment you're replying to said there weren't many good technical reasons to prefer freebsd over linux. I think that's broadly true.
I still really like freebsd though. Unlike linux, one community is responsible for the kernel and userspace. That makes the whole OS feel much more cohesive. You don't have to worry about supporting 18 different distributions, which all do their own thing.
How about Ubuntu and snaps? License needed for certain security updates, etc.
It is an old-school UNIX experience, not great for desktops but excellent for long-lived “pet servers” where long-term stability over decades of service is valued. I treasure it for running small Web servers and shell hosts, instead of Debian/Ubuntu.
It's a pretty rock-solid system, from my memory of the 2000s.
BSDs in general are tightly integrated between kernel and userland tools. FreeBSD has a lot of modern concepts built in that Linux also has, such as Jails and bhyve VM hosting.
FreeBSD has ZFS has a first-class citizen and in my sysadmin opinion, ZFS is one of the best filesystems ever created. While others dunk on BSD for "catching up to Linux" on certain features, BSD equivalents seem to be really well architected. ZFS is one place where Linux (btrfs) is only beginning to catch up. I just learned about bectl (Boot Environment Ctl) that makes snapshotting and rolling back the system partition of installs really easy, and ZFS-on-root is critical to that tool.
For many, having the simple RC init system is a boon over systemd. Services that need started up at boot are defined in /etc/rc.conf, as well as networking and other core services. Editing rc.conf can be done manually or with the sysrc tool.
You might have to use an Ethernet connection though, as the Wi-Fi may not be supported.
