Re: What if the number of distros increases?
Linux Distro = package maintainer (when you boil it all down)
In theory, this just determines how you install and keep your Linux OS updated, and what comes with it by default. But, what matters for REAL is:
* what init system(s) you have available from your Linux distro
* what GUI system(s) it uses by default (and can you CHANGE it?)
* what device support it has (other than going out and finding source and compiling yourself)
* which desktop options you have that are EASILY set up (this includes boot to console)
* what [other] 3rd party software you have available for easy install
* how reliable and close to 'bleeding edge' the binary package versions are
* how easy it is to build from source if you need to fix things or do development work
Any Linux distro that has good support for THOSE things for YOUR purpose is just fine, I say
Many distributions seem to provide these things. My current favorite is Devuan.
However, when working with / evaluating a development ARM board recently, I had to install a version of Ubuntu (only available choice) which was pre-loaded with WAYLAND which i had to IMMEDIATELY SWITCH OUT for Xorg for MANY reasons, and even after being ANGERED by WAYLAND and FIXING IT to use XORG (which was a bit painful) it STILL did not work with the LCD screen afterwards... (not even a change in Linux distro or desktop back-end can fix hardware design flaws). But CHOICE between Linux distros would have led me to that conclusion a LOT quicker.
