Zocker, it's like docker on FreeBSD
- Containment is always a hot topic, and docker has gotten a lot of hype in Linux land in the last couple years - they're working on native FreeBSD support at the moment
- This blog post is about a docker-like script, mainly for ease-of-use, that uses only jails and ZFS in the base system
- In total, it's 1,500 lines of shell script
- The post goes through the process of using the tool, showing off all the subcommands and explaining the configuration
- In contrast to something like ezjail, Zocker utilizes the jail.conf system in the 10.x branch ***

- OpenBSD has recently imported some new code to support the Patrol Read function of some RAID controllers
- In a nutshell, Patrol Read is a function that lets you check the health of your drives in the background, similar to a zpool "scrub" operation
- The goal is to protect file integrity by detecting drive failures before they can damage your data
- It detects bad blocks and prevents silent data corruption, while marking any bad sectors it finds ***
HAMMER 2 improvements
- DragonFly BSD has been working on the second generation HAMMER FS

- They've also switched to a faster CRC algorithm, further improving HAMMER's performance, especially when using iSCSI ***
