The main avantages of Arch Linux are a very recent version of all the packages, a relatively small image footprint and a very optimised compilation of packages. For example it boots within seconds compared to sometimes almost a minute with Raspbian.
On the downside, it is important to keep the OS updated all the time because it is a rolling upgrade system.
But a few month ago, I wanted to add new package and I had to catch-up with the versions of the libraries. In theory, no problem with the command:
pacman -Syu package_name
The upgrade went well without warning, I rebooted... and the system never ever came back...
Total crash! A first, impossible to boot. After a while, I managed to go the root prompt but hardly further. Knowing that I normally used my Raspberries headless, having to plug keyboard and screen really adds to the pain.
I figured out it would be easier to copy the data and to restart afresh.
Yet, a couple of weeks ago, same scenario... AGAIN!
This time I gave up! In the meantime, Raspbian Jessie was out. Trouble is, it is now a pinnacle of bloatware (at least to use as a pure server).
Anyway, while I was at it, I made the switch to a new OS on a new Raspberry Pi 2. I got stung by the new Device Trees Overlay system when I had to change the GPIO 1-Wire pin but at least I ended-up with a stable OS.
The other day, I discovered a new-ish distribution called Minibian which is basically a minimal version of Raspbian.
It works very well indeed and was exactly what I was looking for. There are a couple of differences between Minibian and its huge brother but nothing bad. Video memory split is for example already set to the minimum and you connect straight to "root".
Transfering the image to the SD Card is business as usual:
dd bs=4M if=2015-11-12-jessie-minibian.img of=/dev/sdc
But be prepared to use
apt-get install quite a lot at the begining!
For example, for raspi-config.
apt-get update apt-get install -y raspi-config
And so on...
