- Less SysV Init I can get behind, definitely. But rsyslog is still very useful with lots of networking devices and application stacks using it for remote log capture.
- More Git? Oh please no, it already felt like 30% of my exam was about git.
- Ansible, 100%. I know that it's not a vendor-independent product, but at the same time: yes it is.
- Z shell? Sure, why not. Though any other "regular" shell, like Bash, tcsh etc is also fine.
- ZFS? I've never used it, but that's probably because I don't work with big storage systems.
My wish list?
- Ansible basics.
- Docker, LXC or other containerization hands-on, not just the tiny bit about concepts.
- Setting up an actual web service with httpd or nginx, includingproper TLS certificates.
- Self-signed certs need not apply!
- Load-balancing hands-on, with nginx or even Docker Swarm. I know, K8S is even cooler, but also a bit too deep.
- Not just the concepts, but actual hands-on with OS install automation. Vagrant, Terraform and some of the topics they only discuss briefly in 004.
- I can understand keeping rsyslog for those reasons.
- I only got a single git question when I wrote XK0-004 (which is why I wanted more) - every exam is different I guess!
- Z shell basics and environment files are good mainly because many distros are starting to adopt it as the default shell (e.g. Kali), and macOS does as well.
- ZFS is sooo pervasive on Linux in many of the datacenter environments I work with (as well as on-prem NAS/fileservers) as it's arguably the most powerful filesystem out there (root filesystem on each node is typically ext4/xfs and all other storage is ZFS)
- How did I not recommend docker/podman and LXC/proxmox?!? Awesome and so relevant to so many Linux admin/devops/dev jobs. Knowing why Terraform is good for creating infrastructure (replicatable, can be audited) is very good, but as with so many of the technologies in that space, I'm sceptical if further depth is worth it given the audience and breadth of Linux+ (a lot of IaC is just sweat equity and geared to a specific environment).
- I'd love to see more service configuration - sshd, vsftpd, samba, nfs4, apache2 (with TLS and virtual hosts), named, dhcpd, ntpd, postgres would be my wish list.
