- There will also be a ZFS BoF during lunch of one of the conference days, be sure to grab your lunch and bring it to the BoF room
- Also, don’t forget to get signed up for the various DevSummits taking place at BSDCan. ***
What does Load Average really mean
- Chris Siebenmann, a sysadmin at the University of Toronto, does some comparison of what “Load Average” means on different unix systems, including Solaris/IllumOS, FreeBSD, NetBSD, OpenBSD, and Linux
- It seems that no two OSes use the same definition, so comparing load averages is impossible
- On FreeBSD, where I/O does not affect load average, you can divide the load average by the number of CPU cores to be able to compare across machines with different core counts ***
GPL violations related to combining ZFS and Linux
- As we mentioned in last week’s episode, Ubuntu was preparing to release their next version with native ZFS support. + As expected, the Software Freedom Conservancy has issued a statement detailing the legal argument why they believe this is a violation of the GPL license for the Linux kernel.
- It’s a pretty long and complete article, but we wanted to bring you the summary of the whole, and encourage you to read the rest, since it’s good to be knowledgeable about the various open-source projects and their license conditions.
“We are sympathetic to Canonical's frustration in this desire to easily support more features for their users. However, as set out below, we have concluded that their distribution of zfs.ko violates the GPL. We have written this statement to answer, from the point of view of many key Linux copyright holders, the community questions that we've seen on this matter. Specifically, we provide our detailed analysis of the incompatibility between CDDLv1 and GPLv2 — and its potential impact on the trajectory of free software development — below.
However, our conclusion is simple: Conservancy and the Linux copyright holders in the GPL Compliance Project for Linux Developers believe that distribution of ZFS binaries is a GPL violation and infringes Linux's copyright. We are also concerned that it may infringe Oracle's copyrights in ZFS. As such, we again ask Oracle to respect community norms against license proliferation and simply relicense its copyrights in ZFS under a GPLv2-compatible license.”
