  • I needed to make a docker image based on Core OS (RedHat) and the docker host had to be RHEL compatible. My machine is Ubuntu. To get it to work, I installed Rocky Linux on LXC and docker inside that machine. Turns out there are a lot of security settings isolating LXC and restricting nested virtualization, but fortunately Canonical posts a 20 minute video explaining how to modify the permissions for that use case. I cannot imagine virtualizing much further without the machine refusing to comply!






  • If you need to reinstall your OS you don’t have to mess with the home drive. I use Linux for work and some of my clients actually require all data to be stored on a separate disk or partition from the applications. It also makes your backup strategy simpler and is transparent to you as a user.

    2TB is too much space for an OS disk, especially since you’re not going to dual boot, so might as well get a bigger data directory and speed.

    My workstation is a PCIE Gen 4 Threadripper. I’ve got a multifunction card with a couple 2TB Gen 3 NVMe drives that I striped and the bandwidth is identical to a single Gen4 4TB NVMe. Obviously you’d need a backup strategy to handle the case of a drive failing but that is true no matter what.
