linux
About a year ago I decided to revamp my personal cloud. Main objectives were to make it more manageable and use as much pre-made software suites as possible instead of maintaining my own. This article is about what software I chose, which software it replaced as well as reasons why this was done. Oh and of course, I’ll start with hardware.
I am trying to document how much of an impact VFIO has on gaming performance. More benchmarks will come in the future, but for now, let’s look at Forza Horizon 5.
As I was migrating my whole system over to btrfs the other day, I came across my
docker volume which was already btrfs and using subvolumes. This was of course
intentional, however, I had no idea how to properly move those subvolumes to the
new disk.
With ZFS on Linux, it often happens that zpool is created using disk identifiers such as /dev/sda. While this is fine for most scenarios, the recommended practice is to use the more guaranteed disk identifiers such as the ones found in /dev/disk/by-id. This blog post describes 3 methods how to change the disk identifiers in such zpool after it has been created. All this without migrating data, adding disks or having physical access to the machine.
Alpine Linux is an interesting Linux distribution meant for embedded devices. Its key ability is running on a diskless system. Unlike other embedded distributions, it remains very usable for desktop use. The recommended, standard edition, runs a hardened Linux kernel with grsec and PaX patchsets. This strengthens the security of an already secure operating system. I will explain why I chose Alpine as my daily driver and share my opinion on its package management, memory footprint and shortcomings.
