Hey; Linux refugee here. I want to have a bunch (5-10) of freebsd cattle-style servers to run a service on. What’s the preferred infrastructure as code style approach to setting them up? Some will be bare metal with kvm console access. Some will be VMs. They will be heterogeneous and not in one DC. I probably don’t need zfs for this application (raw iops matter more than snapshots, etc). I have previous experience wi…

> Is there anything FreeBSD can do that, say, Debian cannot? If you asked the opposite (what can Debian do that FreeBSD cannot) I would have more to say and it would mostly be preceded by "I know FreeBSD is not Linux but ...". Whenever I need to do any sort of maintenance or inspection I have to look up the equivalent commands for things like `lsblk` and something nested in `/usr/etc/...` when I'm used to finding it…
Lack of docker support? Docker is available on macOS through emulation yes but bhyve is a thing… so why not? :-)
One of my favorite FreeBSD features is first-class support for ZFS boot environments. These have been working in FreeBSD/Solaris since 2008[0]. Having each boot environment available as a ZFS snapshot capable of being managed the same way as any other dataset, capable of being sent and received, is such a powerful feature. I dilligently watch the immutable / atomic Linux space to see when something implements this in…

> Is there anything FreeBSD can do that, say, Debian cannot? Yes. Emulate traffic latency using IPFW and dummynet[^1]. There is no Linux (or OpenBSD, NetBSD) counterpart. The ZFS implementation is less buggy. [^1]: https://man.freebsd.org/cgi/man.cgi?dummynet

On Linux, ARC memory is reclaimed using the kernel shrinker API which has historically been a problem. There has been several bugs leading to OOMs or system freeze due to high memory usage on systems that use ARC heavily.
On FreeBSD ARC is integrated directly with the VM subsystem. The stack is simpler, less bug-prone.
Now this is not a ZFS algo/whatever problem. It's an implementation/subsystem issue but it's still something to keep an eye on for the ZFS admin.
ps. I'm using ZFS on Linux for 15 years on a self-hosted, home backup server and only once I've had mem issues leading to crashes when I misconfigured the ARC. So it's fairly _stable_ but still not FreeBSD-level stable.
Can we say FreeBSD is more secure than Linux, because it’s smaller and less of a target? Not clear!
My home server has been running FreeBSD for ten years now, and it has never let me down. Except for one time I got fresh with /dev/speaker and triggered a spontaneous reboot (I don't know if it's FreeBSD's fault or the hardware, though). I delayed upgrading to 15.0 after it was released, but last weekend I finally did it, and it left me wondering why I hadn't done it sooner, because it went quickly and smoothly. Is t…
ZFS on FreeBSD is first class. I had an old FreeNAS raid z5 array on 5x 500GB disks that I wanted to check 4 years after decommissioning the system. I put together a temporary machine with all the disks plugged in and without doing anything the live FreeBSD image found and configured the array. I was instantly able to look through the file system and even dump it to my current FreeBSD server with almost 0 effort. I w…
Also, a few years ago the FreeBSD people decided to throw away their own ZFS implementation and import the linux one (OpenZFS) because they couldn’t keep up with the development pace.
Nowadays ZFS development is collaborative but in each major freebsd release it’s clearly marked which OpenZFS releases they imported in the FreeBSD codebase.

Lack of good NFS support? When we benchmarked it last it was 10x+ slower than running on linux (ubuntu). Also lack of collective mindshare. I use FreeBSD at work every since day and while I don't hate it, I do wish we just used Linux. There are more guides, tools, etc for Linux than for FreeBSD. Yes, as a comment in this sub-thread stated, jails exist but everyone knows docker, not jails. So even with jails apparentl…
>>maybe I'm "holding it wrong" (always a strong possibility) Yes. You are holding it wrong. And it's obvious from your comment.

Being that said, on FreeBSD 15, I believe I've found a serious bug: when I disconnect a USB optical mouse on the "Lenovo 16 G7 ARP" the system completes freezes and reboots, I guess it reaches a kernel panic. It took me a few disconnections of the power, ethernet and finally the mouse to detect this condition.
Surprinsingly this does not happen if the device is wireless (I tried to remove the receiver of a Trackball and the system keeps working just fine). I find this really weird and don't know if actually report it in the FreeBSD forums, maybe is just a glitch on this particular laptop or it has something to do with the touchpad, just guessing here.
Putting this particular issue aside, I'm extremely happy that almost everything works with little or no effort on a recent/modern laptop.
BSDs in general are fantastic OSes.
My personal issue is that I do not believe FreeBSD will give me a smooth experience to get my GPU and what not running. On Mint Cinnamon, I only had to install the latest supported kernel to get my RTX and WiFi6 card recognised.
Debian, the reason why I run Debian as a server everywhere, even in my 3D printer is because it just work, and not just that.
I only run Debian Netinst version, that means to only install standard system and SSH, text mode is the way.
We are talking about 300MB of memory being used by Pihole + Unbound Recursive DNS of 512MB running on a Debian 13.
Disk space?? 1GB or so I guess.
These are my blockers to even try raw FreeBSD, lack of proper hardware support and as a server even if I remove everything I can, I do not imagine FreeBSD running with 300MB/1G of resources.
Not to mention if you work in IT in any way, the last thing you wanna is fighting the system you use to solve another problem, that is why I left Ubuntu after 13years or so, it is a Windows within the Linux world now.
A distro Linux must just run, no dramas, no issues, major system release goes like nothing happened. That matters!!!
When I tried FreeBSD, I was also blown away by the manual, so simple, such high-quality documentation. I think what I liked the most is that it felt coherent, unlike modern OS like Linux and Windows. I think macOS might be the most cohesive of the popular OS's.
I could say some nice things about MacOS, but it certainly is not “cohesive” any more.
