As a Linux newbie, all I know about Arch Linux is that it is a DIY distro where you assemble the entirely of the OS by scratch. Somehow it feels like it is too easy than it needs to be, even if it is primarily meant for experienced users. I imagine it to be less like building your PC from parts bought from the market and more like building each and every component of the PC by scratch along with building the PC, which I assume to be much harder for the average consumer. It seems absurd how it is possible for a single person to incorporate the innumerable components required for functionality in a personal system that does not crash 100% of the time due to countless incompatibility errors that come with doing something like this.
I would like someone to elaborate on how it feels to ‘build’ a system software by yourself with Arch and how it is reasonable to actually do so in a simple language. I do have some experience in programming, mainly in webdev, so it’s not like I need a baby-like explanation in how this works but it would be nice to get to know about this from someone who could understand where this confusion/curiosity is coming from.
The best way to keep an Arch daily driver stable is to use a CoW filesystem like btrfs or ZFS and use a pacman hook that takes a snapshot before package installation or updates. If you run an update or package install that breaks something in an inconvenient way 20 minutes before you have to be on a call using said system you just revert to the snapshot, reboot and you’re rolled back. I’ve run Arch as my daily driver like this for 4-5y now and can count the number of times I’ve needed to roll back like this on one hand (mostly I just don’t run updates when I’m under time pressure.) Arch really doesn’t break in a major way all that often once you’re over the first 6-9mo of the learning curve, ie: it usually stops breaking once you stop fucking around and poking things while you’re learning about them.
I wouldn’t recommend Arch as a daily driver to someone who isn’t generally competent at linux admin and troubleshooting, it’s a handful for people who aren’t up on their skills yet. On the other hand it definitely will help you develop those skills, that just takes some time. A snapshot and rollback system gives you the freedom to break most things with a reliable way to roll back to a known good state afterwards.
