From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Not really heavy lifting, I'm just running the Xanmod kernel, and need to turn on some features I need for eBPF development. I'm also keeping up to date with kernel releases, so every 6 weeks or so I need to rebuild.
The ARC runs in RAM, but is generally best when it's given:
Conditions great for a server but not so much for a workstation. I don't intend for my cache misses to go to spinning rust, so I have 2 2TB NVME drives. SSDs are cheap as chips currently.
The L2ARC is a victim cache of the ARC, and while it is persistent it's still much more effective for me to just use a NVME drive for my pool.
Just went through Xanmod's page: the list of features provided seem exciting, although I don't really know much about some of them. Do you need these features for eBPF development?
Well, you're right: ARC is best used in a server. What problems did you have with BTRFS that prompted you to switch?
I use Xanmod for gaming (fsync & related tweaks), but need other flags for development on the same machine.
My issues with BTRFS were mainly in their userspace tooling; ZFS volume management is just glorious, it felt like a significant downgrade to use BTRFS.
