I have not looked at it recently but for any access greater than ~ 16K ZFS was more efficient than UFS. It's just one partial data point but the conventional wisdom that ZFS will use more cpu is not an absolute truth. Even more so for RAM, ZFS with 128K record make efficient use of metadata.

For 99.999% of humanity, "free" means that they don't have to pay for it. For GPL "free" does not pertain to its use by humans at all. Instead "free" for GPL is about preventing the "enslavement" of the source code itself ("enslavement" means distribution of binaries without source code), as if the source code was a living breathing creature. Due to the ambiguity now associated with the "free", I will prefer the term "open source" and use some other term besides "free" to describe any encumberances caused by the license.

In the case of the atheros code they share with BSD, they supposedly agreed to dual-either/or-license their improvements, but they don't have to, and they can change their minds. If they didn't, and Linux got a lively ZFS community, then there'd either be huge duplication of effort or ZFS in Solaris would fall behind to the point that Linux would become the definitive release. I agree that's far from ideal. But Linux developers have the absolute right to decide how they want to spend their time, and I don't agree they're being irrational by preferring to work on btrfs than under the CDDL.

OpenWRT is arguably source-based too. but Gentoo is extremely clumsy to my view: I find USE flags to be a terrible mistake because they hide bugs and make dependencies no longer automatic. It would be a lot more workable if I had bootable ZFS snapshots in Gentoo to give rollback protection when doing security-fix updates. Also I think they don't do enough (any?) branching for stable systems---they sort of think they can have ``stable'' and ``experimental'' branches both continually updated, with no tagging, all the time, which makes all updates equally risky instead of batching things into major-infrequent and minor-frequent updates. In that sense I guess it's just like opensolaris. but yeah, that OTness aside, Sun's deliberately crafting their brand new CDDL license to be incompatible with the GPL isn't exactly in the spirit of free software. BSD is also not in the GPL camp, but the mainstream of BSD has altered their licenses where possible to add GPL compatibility. The GPL camp moves in the same direction: the GPLv3 added changes to slightly improve license compatibility. That said I don't really understand why ZFS can't be a Linux kernel module, since Linus's ``interpretation'' of the GPL has almost reduced it to LGPL within the kernel. Why his ``interpretation'' should have such weight when he doesn't hold all the copyrights I've never understood either, but so far all these big companies distributing binary modules seem to take it as law. This thread seems to say the same: http://groups.google.com/group/zfs-fuse/browse_thread/thread/1219db6af605f792 so, maybe it is not really a license permissiveness issue, so much as a license preference issue that you cannot convince very many talented Linux developers to do free work for you unless you give their efforts the protection of the GPL. The one willing to work without GPL protection only offers enough free time to do the easier FUSE port. :) j> I like you open folks, much much more than the L-open folks.

I had Gentoo here and have lived to tell the tale. It would be a tall tale indeed if I was to claim to have recieved some sort of scars or undue stress from the experience, or even significant discomfort. The main issue was with burning CPU building new versions of software, but that is much less of an issue now. I do not claim to be in right mind without someone paying me money to do so. Regardless, I am not aware of anything preventing someone from creating a distributable source patch to insert ZFS into the Linux kernel, as long as the end user builds and installs their own kernel. While it may be difficult for some Linux users to understand, the source code is actually available for the Linux kernel.
