As someone who isn't very familiar with NetBSD aside from the "It runs on a toaster!" meme, what does NetBSD bring to the table compared to something like FreeBSD if you want to run it on a common architecture like x86?

Congratulations on the release, by the way. :)

I run FreeBSD on my home server (because of ZFS). But I use NetBSD every now and then.

Things I like about NetBSD:

- It has support for both Dom0 and DomU Xen domains.

- It is very clean and portable code, you can build it on any *nix machine and get install media, just do ./build.sh release; ./build.sh iso-image

- There are fun experiments being done. Like rump kernels and Lua in kernel space

- It's dominated by hobbyists.

How is it better than the alternatives (linux and other bsds)?

> Lua in kernel space

This sounds like something which, were it done by Microsoft, would be taken as evidence of terminal senility on the part of the technical leads. What is NetBSD's reasoning for doing it?

Why NetBSD?

- For its excellent backward compatibility: NetBSD 6.1 is still able to run a.out binaries built for NetBSD 1.0

- For its system-independant build system. Building NetBSD needs a POSIX system with a C compiler, which does not need to be NetBSD. It first builds the tools for the host, including the compiler itself, and then the target NetBSD system, which may be for another CPU.

- For its machine-independant drivers. Have a fancy platform with an odd CPU? If NetBSD has a driver for a chip, it will work as is, no need to port it

For me the biggest advantage to running NetBSD on x86 is that it includes many of the features of other BSDs (simplicity, documentation, PF, CARP, etc..) and it runs great as a Xen Dom0/DomU.

Because NetBSD runs so well as a domU I'm really surprised it's not much more popular at many of the larger Xen-based cloud hosting platforms. I've heard it also works well with KVM & virtio but never tired it myself.

I just tried it on RHEVH the other week, and it -runs- well (easy to setup, just works, virtio works as expected), but on shutdown, would jump to kernel debugger.

I didn't get shutdown issue sorted, or benchmark performance, but it's really easy to setup and start playing with.

I haven't looked at in in years, but their code tends to strive for more simplicity, to ease portability. Which usually means that they can't make the same sacrifices as FreeBSD does, especially regarding SMP and multi-care systems. But I've heard that this got a lot better in recent years and by postponing that skipped a few errors that FreeBSD made.

Also their package system (pkgsrc) is a bit different from FreeBSDs ports, and those tend to be highly subjective, regarding ease of use and the amount of software packages covered.

My info might be a bit outdated, but I think NetBSD provides the best Xen support.

I think that simplicity is the big difference between {net,open}bsd and other operating systems. It is amazing how small some of the standard programs are compared to GNU.

If you ever want to read some excellent C code just go and look at the source for some userland utilities in OpenBSD.

The current FreeBSD installer is quite bad, I was unable to install a system with a NTFS partition left untouched. I wasn't able to create the partitions manually because it complains about "invalid arguments".

Also, when leaving out the bootcode partition, it happily installs and leaves you with a non-bootable system.

In addition, the pkgin tool is a really handy tool to install binary packages. I'm running in a VM with not too much memory and compiling would take ages or fail because of the amount of memory that compiling requires.

I also kinda like the firewall but YMMV.

How is the hardware/driver support for NetBSD in comparison with FreeBSD or Linux?

Is it better, worse, or about the same? I'm considering using a Mac Mini G4 as a server, and was wondering whether to put FreeBSD, NetBSD, or Linux on it.

I know all of them will have drivers for the G4, but if I wanted to put any on a newer computer, how would the hardware support be?

octotoad13y ago

NetBSD and OpenBSD have had good PowerPC support for quite some time, whereas FreeBSD's port is relatively new. You'll want the 'macppc' port for any Apple system.

Been a while since I've used a PPC, but I'm guessing hardware support under Linux and NetBSD probably wouldn't differ too much these days.

I do remember Linux being slightly less fiddly on PPC when it comes to boot loaders.

sliverstorm13y ago

To my knowledge, you can safely assume all BSD variants run behind Linux in terms of driver support for new hardware.

kev00913y ago

Pathologically, older SPARC and SGI MIPS boxes are probably a lot better off on OpenBSD where they are actively developed for and tested. Linux casts a wide net but has a lot of bit rot in the dark corners of it's hardware support.

Run FreeBSD on it...NetBSD on PowerPC essentially requires a dual-boot or Apple_BOOT partition. FreeBSD has a cleaner boot (amongst BSDs, anyway...I do like yaboot).
