I have, very old Rasp Pi2 now, it started with a hacked Fedora 22 image (ubuntu kernel IIRC, then fedora filesystem, something like that) then F25 become official... and I've just upgraded that over time. I know there's a heap of love for the rasp pi, but man, it can get super frustrating at times: I've lost count of how many times the SD card's have crashed out on me, and I run the OS off the USB HDD, to keep SD card wear to minimum. Powering the bugger is an issue too: Must have far better USB power supply than you'd think.
My ARM device I'd like to get Mageia on, is the original ARM Samsung Chrome book. I did mess around ages ago, and get a 'kinda' working Mageia but coasting on Crouton's tail coats: Here's mine:
https://github.com/xboxboy/cromec I wasn't able to get it pulled into main, because I hadn't been able to (IIRC) get URPMI emulated using the Google OS CLI tools, so the project leader wanted that fixed :/
Now a days, I think Google dropped support for it, so we could blast the Google OS off it, and just run Mageia.
I have a little Asus XT205A, that Martin did all the work on (64 bit CPU with 32 bit UEFI: YUCK) and we have that running nice, although a kernel update has broken that, I need to repair that: The partition naming is the issue, I just need to spend some time on IRC with a helpful soul and we'll have that back in working order.
Hardware support has always been a strong point of URPM* based distro's. I still remember the first time I installed Mandrake 9.0... OMG, it blew me away! I was young and doing stupid things with PC's back then, and blasting away windows after messing with settings I didn't know about was done regularly: Between Windows 98, ME and XP I must have installed them 30 times I'd say,,,, it seemed each time was inconsistent with the previous! Drivers were a PITA, disc after disc, download after download... etc etc... But Mandrake, slip in 2 cds, and it's done: And beautiful, and fast!!!!
Today is the same I believe: Mostly I just upgrade the OS. Mageia has treated me VERY well. I have raid issues: But that's an edge case.... and way old hardware, using Fake raid: I tell everyone to avoid it now!!!!
I don't do social media much, but if a few guys got the latest Pi's up and running, showed how to use them as file servers: download boxes, media/music streamers, printer servers etc... You could start to build a bit of a community. That's the hard part. Ubuntu/Raspbian have massive support. On IRC i speak with some of the fedora devs now and then, and Broadcom (Rasp pi's manufacturer overlord boss) is funny with some drivers etc. I haven't asked in a while, but for a long time, even the boot process wasn't open source: Not the end of the world, but Fedora try to be 'open'... Mageia walks a beautiful balance of open/closed sourced stuff:
For me the draw to Mandrake initially was the Xbox project (Mandrake 9.0 had an original xbox release... no, I never could get it to work) then Mandriva 2005 LE had true official support for xbox... but once I installed on PC, and seen MCC: OMG, I was sold... For a few years I messed around with trying Ubuntu/Fedora... probably others... They all work fine, but NONE have MCC. Yes, CLI is great, and I can use it usually enough to get out of trouble, but MCC is just epic. Install a printer, partition a HDD, mess with video drivers etc etc... MCC just get's it done.
Even when X wont start, CLI version of MCC is great!
So I think that's what you have to sell to 'rasp pi' newbs.
Look how easy it is to get a web server up: Install Mageia, then "urpmi task-lamp"... done!! None of this aptget, or dnf install individual packages...
Adding a new HDD for more storage? "diskdrake"... boom, graphically set up your partitions!
I think even traditional pc versions could do with some more 'pushing'. If you're on social media, post that you just upgraded from 7 to 8 with no issues. Post that you installed a new printer in 4 clicks. Post that you could recover data from a wiped USB stick (Still blows my mind that I actually did that! Accidently wrote over our wedding pictures back up USB.... can't remember what I used now, "ddrescue" rings a bell... got everything back: Seriously!).
I've got a couple of laptops that have reached the end of their 'portable life" ie: One was bought purely for the screen to repair another laptop, the other is my wifes i9, that is literally falling apart. I think these are going to be repurposed as my home server/lab, and virtualize everything this time. My pi has served well, but it's a PI2, it's network speeds suck.
Will I get a pi4 etc??? Not while I have so many pc's laying around unused that I can repurpose.. Yes the pi uses less power. I just can't be bothered with the sd card and power issues (although I think pi4 can boot from USB?), network speeds (IIRC it's faster networks now too)etc etc anymore.
But I would love to see Mageia get some traction in maker world.
