First of all, thank you for this! This effort is very much appreciated and will definitely make it easier to parse through Linux; especially for beginners.
Having said that, some personal nitpicks of mine:
How do the ‘offspring’ of Mandrake/Mandriva compare to one another? IIRC, there’s ALT, Mageia, OpenMandriva, PCLinuxOS and ROSA.
I’ve also come to the understanding that what set Mandrake apart from its peers was its polish and user-friendliness. Which, harbored a great community back in the days. Currently, however, this role is fulfilled by distros like Linux Mint. Furthermore, most distros are relatively straightforward anyways. So, my other questions would be:
Thank you for sharing your experiences!
May I ask you what made you pursue an Arch installation in the first place?
