I doubt that anything could have changed, because OpenBSD has not implemented any new file system and a few years ago they have even removed the support for "UFS with soft updates", which is a file system that is not affected by power failures, but the OpenBSD developers could not maintain it, because apparently today nobody understands it any more. Thus there is no doubt that the UFS variant used by OpenBSD remains…

I have some knowledge of the BSDs and they all are but OpenBSD is particularly belligerent about Licenses and they consider ZFS "non–free" on par with the GPL(I know I know) which is a huge barrier to entry into the kernel. They only begrudgingly accepted clang after they changed their license because there was no real alternative. Before that they had been using some ancient GPLv2 gcc. Truth is, I've never had a cat…

> they consider ZFS "non–free" on par with the GPL Why isn't it? The CDDL is basically the MPL, which in-turn is basically the LGPL. The jihad against the GPL by FreeBSD and conveniently ignoring the CDDL being weak-copyleft was always ironic to me. > and the devs probably haven't had one either solene@ left and stated the filesystem as a supporting reason: > I have grievances against OpenBSD file system.
