Here is some news that both excited me and gave me pause. In its annual 2025 retrospective, published today, Arch-based CachyOS, widely popular among Linux gamers and heavily focused on performance optimization, reveals plans I did not expect: an expansion into the server space.
“In addition to our ongoing PGO and AutoFDO optimizations, we are developing a specialized ‘Server’ Edition for NAS, workstations, and server environments. We intend to provide a verified image that hosting providers can easily deploy for their customers. This edition will ship with a hardened configuration, pre-tuned settings, and performance-optimized packages for web servers, databases and more!”



That’s why I’m asking, what’s the difference? Which defaults? I have never used CachyOS and have no idea what it brings to the table. I use Arch for ~7 years, and I’m no looking for a replacement. Especially an Arch based one. Yet, I’m curious of the difference, and why one would want Cachy, especially as a server.
I too run an Arch and am happy with it, and I would like to know why Cachy. The only reason I can see is having x86-64-v3 packages instead of baseline. That is nice, but on it’s own doesn’t feel worth the effort of switching over.
Defaults don’t matter to me much, as I automate and manage my system config in git (using a tool I wrote myself: https://github.com/VorpalBlade/paketkoll/tree/main/crates/konfigkoll inspired by https://github.com/CyberShadow/aconfmgr). It makes it a breeze to set up a new computer as I want it.
I don’t want to spill some memes worth Arch elitism here, but I just doubt Arch derivatives crowd knows what x86-64-v3 thing is. Truth be told, I barely understand that myself. So I guess the difference should lie somewhere else. My previous research showed that the crowd is afraid of no installer installer, but these days Arch has some kind of installer, doesn’t it?
I’m just struggle to grasp what does it have, what those defaults are? A DE and whatnot? Is it just an opinionated Arch? Looks quite popular for everyone and their dog to have their own opinionated Arch this year, isn’t it?
