Recently I meet Garuda. In my opinion it is the best direvative from Arch Linux. Thanks for developers and mantainers!
I installed Garuda dr460nized on my wife's PC, and I installed Garuda bspwm on my office PC. But, in my home I haved old installation of Manjaro Deepin Linux. And one day I wanted to switch to linux-zen kernel I learned a terrible secret: Manjaro devs use their own repository based on Arch, BUT the packet names and the packet versions are the same!! But the content is different! What a dissapointment. And these repositories are very limited, they do not have linux-zen.
I didn't want to reinstall the whole system from scratch. So many programs on it's own place. So I decided to migrate to Garuda step-by-step.
It wasn't just! And I do not recommend this path to anyone. I started by deleting everything related to deepin, then to manjaro, then install chaotic-keyring and chaoric-aur, then install minimal base of garuda related packages. Such as garuda-{hooks,update} grub-theme-garuda linux-zen{,-headers} mhwd-garuda-git ananicy-cpp and others (sure it's not all details) It helped me a lot to have two other systems with Garuda on board. By tries and errors, I brought the system into a consistent state. It took about 4 hours with my slow internet (~200KiB) Much less if I reinstall everything from scratch and reconfigure. Ofc I didn't get BTRFS and snapper, but everything else is good!
I don't know why I wrote this opus. Just wanted to share that this is possible if you have the minimal skills and patience.
Nevertheless, I advise you to install the original builds of Garuda Linux. This is how you get support! Thank you. Love you.
Manjaro to Garuda sounds difficult. Well, congrats I did winesapOS to Arch Linux and faced problems with that, I'd expect your migration to be much harder.
There comes the real question: Will you face issues because of this in the future??
In fact, I migrated because I experienced more problems with manjaro. I'm not a beginner and I know how distributions are built. I hope I did everything right.
