Thoughts on Chrome OS

After a long time of ignoring this platform and only ever having tried CloudReady (which this is based on), I tried to install ChromeOS on some of my older machines. While the older ones like Thinkpad X200 performed poorly as expected, newer machines performed well. I’ll elaborate on a few different points in which I see the value of this OS.


My personal cloud server upgrades

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.



Moving many btrfs subvolumes to another disk

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.


Changing disk identifiers in ZFS zpool

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 as a desktop operating system

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.
