The NetBSD project has announced two important stability updates for its highly portable operating system.
The NetBSD Project is pleased to announce NetBSD 5.1.5, the fifth security/bugfix update of the NetBSD 5.1 release branch, and NetBSD 5.2.3, the third security/bugfix update of the NetBSD 5.2 release branch. They represent a selected subset of fixes deemed important for security or stability reasons, and if you are running a prior release of either branch, we strongly suggest that you update to one of these releases.
Details on the two updated branches of NetBSD can be found in the release notes for NetBSD 5.1.5 and NetBSD 5.2.3.
Well this is just my opinion but I think NetBSD is the best BSD because it is the only one that properly supports systemd at this point.
As everyone knows the status of systemd support on OpenBSD is still uncertain and it isn’t likely any progress will be made until Theo de Raadt is out of jail (selling 3d printable plastic fire arm models, don’t ask).
Now that Yolanda (born Jordan) Hubbard has made it clear that systemd is too advanced for FreeBSD that OS can’t be considered for serious work either.
Darwin is written in C# so there might be difficulty porting. Looking at the other BSD flavors I think only Emacs is possibly powerful enough to run systemd.
