Fangtooth BETA Code Freeze, Compression Comparison, Kris talks BSD vs GPL | TrueNAS Tech Talk E012

In this episode of TrueNAS Tech Talk, Kris and Kris provide an update on the Fangtooth BETA, including the internal code freeze and expected release timeframe, and encourage users to test the Incas LXC containers. They discuss upcoming support for selecting IP addresses for apps, cautioning about compatibility issues with Electric Eels. Kris delves into compression space-saving methods like LZ4 and Zstandard, comparing their performance and compression ratios, and touches on block cloning and deduplication. Kris then shares his evolving views on open-source licensing, contrasting the BSD license with the GPL, and reflects on the impact of each on kernel development, ultimately arguing for the GPL's role in ensuring the long-term openness of foundational software like the Linux kernel and TrueNAS. Finally, they address an audience question about migrating VMs to the new Incas backend in Fangtooth, explaining the cutover approach and the need to re-import VM disks.
