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.

    Daily Arch user here. The process of configuring an Arch install is perhaps not as difficult or mystical as you are imagining. I would say it is more like your first analogy: picking what off-the-shelf parts you want for a system and then putting them into a case. I think what you are describing is more like Linux from Scratch.

    Installing Arch is effectively taking the steps performed by the installer .iso disks which every distro uses and instead doing it manually with CLI commands. You use CLI commands to partition the drive, create a filesystem, install a basic set of packages, then chroot into your system and use the package manager to install the rest of the packages you want. Aside from editing a couple config files, there is zero coding involved. The exact steps vary from guide to guide, but a basic outline of what I do is as follows:

    • First, I download the Arch iso and write it to a USB.

    • Once I boot up the install USB, I use iwctl to connect to my wifi for the packages I will need to download,

    • then I use fdisk to partition the drive I want to install to with an EFI and linux filesystem partition (You might also make a swap partition at this step but I typically use a swap file on my filesystem partition).

    • then you use mkfs to create filesystems on the EFI and linux filesystem partitions.

    • Then I use genfstab to make the /etc/fstab file

    • Then, I use pacstrap to install the base packages like pacman. Then I mount the filesystem and chroot into the new partition.

    • From there, I basically use pacman to install all the packages I need, including the linux kernel (I use linux-zen), the DE (I use KDE), the boot manager (I use Refind), and everything else. There are a few cleanup steps like setting the locales and time zones, etc. but that is about it.

    I suggest watching a guide on youtube, which was how I learned, or installing something like Arcolinux or Endeavour, which simplifies the installer into a series of checkboxes to select what DE you want, etc.
