What’s the point of it?
OpenBSD = Security
FreeBSD = The main UNIX-like
NetBSD = ???
Based on the name of have assumed it’s be used in things like network appliances but in 20 years I’ve never seen a single device use it.
Yes, it is mostly appliances, but an (informal?) stated goal of NetBSD is too run on all computing hardware.
- FreeBSD = user-friendly free Unix (plus ZFS and jails 😀)
- OpenBSD = very secure free Unix (no ZFS 🙁 but has the VMM hypervisor 😀)
- OpenIndiana = user-friendly free Unix that runs old Solaris software (plus ZFS and zones 😀)
- NetBSD = runs on any computer chip ever built within the past 40 years (some ZFS support, but no zones, jails, or VMs 🙁)
Naturally, that makes NetBSD a good choice for appliances, especially ones that might only have limited memory.
(Here is a quick explainer on the difference between Jails, Zones, Containers, and VMs)
EDIT1: someone pointed out to me that ZFS is not supported on OpenBSD. Sorry about that everyone.
EDIT2: there is a ZFS driver for NetBSD
There’s no ZFS support in OpenBSD is there?
No, but I think someone made read only support for ZFS available on OpenBSD. Freebsd is obviously the best for ZFS. It works on NetBSD too.
Thanks, I had to double check that but you’re right, ZFS isn’t on OpenBSD. What a shame. Anyway I edited my above post.
But there is zfs support in netbsd… https://wiki.netbsd.org/zfs/
According to the wiki, ZFS “works well” but doesn’t seem to be as stable as in FreeBSD or OpenIndiana, and is not enabled by default so you have to update your
rc.conffile to build the ZFS drivers.
“I just threw a dead squirrel in a shoe box and installed NetBSD on it.” is one of the bash.org quotes I still remember.
And damnit we did it too
From “back in the day” the big claim was that NetBSD would run on anything. Portability seemed to be their major goal.
I think the point is network appliances but it seems mainly used by hobbyists from what I’ve seen.
If you look at the supported platforms you kind of get an answer here. There’s support for the m68k Macintoshes and other similar ancient devices still.
The main point was always portability, and the ability to run NetBSD on basically ANYTHING.
There’s no specific point in any of *BSD. They all are general purpose OSes. NetBSD forked from FreeBSD, OpenBSD forked from NetBSD. Conflicts between developers were main reasons for that.
NetBSD didn’t fork from Free iirc. They took 4.4 BSD and started developing it themselves of the net.
Theo de Raadt was kicked out of netbsd, and started OpenBSD.
Yes, you are right. Both FreeBSD and NetBSD are based on earlier BSD systems. Anyway there are no fundamental differences between them.
no fundamental differences between net and freebsd?
No such ones that would make one of them unsuitable for some task that another copes with.
What the hell??
They evolve differently. Saying *BSD is like 4.4BSD is still developed by ucb to provide a single base for all BSD.

Absolute BSD (No Starch Press, 2002) was my first technology book and was written when the various BSD operating system had more in common than they wanted to admit. The second edition, Absolute FreeBSD (No Starch Press, 2007), came out after the BSDs had diverged, and detailed FreeBSD’s advances in the previous five year
Pretty much like all Debian forks. They’re all forked from Debian because of conflicts between developers / different ways of seeing things. :P

OpenBSD = Security
It is actually correctless. OpenBSD = Correctness + Simple + Free (free from copyleft too)
FreeBSD = The main UNIX-like
Citation???
NetBSD
maximum portability??
But up to NetBSD 10 (at the time writing it was not released) YOU DON’T HAVE SSL CERTIFICATES INSTALLED IN THE BASE SYSTEM !
That’s my warning :)
And then you have NomadBSD if you need an OS in a usb stick :)
NetBSD, from their own website:
The NetBSD Project’s goals
A project has no point if it doesn’t have goals. Thankfully, the NetBSD Project has enough goals to keep it busy for quite some time. Generally speaking, the NetBSD Project:
provides a well designed, stable, and fast BSD system, avoids encumbering licenses, provides a portable system, which runs on many hardware platforms, interoperates well with other systems, conforms to open systems standards as much as is practical.In summary: The NetBSD Project provides a freely available and redistributable system that professionals, hobbyists, and researchers can use in whatever manner they wish.
Based on the name of have assumed it’s be used in things like network appliances but in 20 years I’ve never seen a single device use it.
The name comes from being develop over the internet, when that was still a pretty new concept. It’s pretty popular among Japanese ISP’s iirc.
If you’re at all interested in unix, you should try NetBSD. Open has security as a focus…although some of that is overstated imo. FreeBSD is clearly targeting servers, even if it is all purpose.
NetBSD is less popular, but it’s clean, lightweight, portable, has pkgsrc. Think of Net as a cross between Open and Free.
I think OpenBSD, FreeBSD and NetBSD are much cleaner than Linux (evidence: Chimera Linux)
you mean chimera using BSD utils instead of gnu?
yes
