ZFS focus on Ubuntu 20.04 LTS: ZSys for system administrators

Didier Roche continues his series of articles on ZSys and ZFS in Ubuntu 20.04 LTS. The basics were covered so we are warned it'll start getting more technical with detail directed to System Administrators. With the aid of diagrams, plus referring back to prior articles, Didier gives us more administrator specifics : such as tweaking log output, streaming specific clients and more - in this long and somewhat detailed post geared for sysadmins. An invitation to help with improving logs via contributions is offered, as well as a link to the discourse thread.

ZFS focus on Ubuntu 20.04 LTS: ZSys partition layout

Didier Roche this time covers what happens on installation, and what ZFS datasets are created. Examples include screencaptures, explanation of why bpool is separated from rpool and complexities of grub, swap partitions over swap files, mount order and the ZFS mount generator. Finally Didier touches on tweaking and a note on taking care.
