I’ll start with mine. yes part of this was to brag about my somewhat but not too unusual setup. But I also wanna learn from your setups!
Anyways: I primarily use Gentoo Linux.
I have two headless servers: a Raspberry Pi 4B and a Oracle cloud VM (free tier). Both running OpenRC, and both were running mainline kernel with custom config (I recently switched the Pi to PiFoundation kernel due to some issues). The raspberry pi boots from SSD and has no sd card inserted.
Both servers were running musl libc instead of glibc for a while. This gave me a couple of random issues, but eventually I got tired and switched back to glibc.
I have a desktop running gentoo and a laptop running arch, but hoping to switch the laptop to gentoo soon.
Both are daily driving wayland (the desktop had nvidia card and used for gaming). The desktop is running a kernel with a minimal config that compiles in 2-3 minutes.
What’s your unusual setup like?
Now, not so unusual, I have pretty dull and standard “gaming” type PC running stock Debian, but about 20 years ago as a broke mofo I was running a phpBB forum off a wheezing Pentium MMX laptop with no screen (got ripped off a year prior) on Mandrake Linux. The whole thing was just loosely sitting under my bed. Managed to get a userbase of just under a hundred people before I lost interest. I was using Webmin to manage it from another PC.
I had to connect up an external monitor every time I needed to do something I couldn’t do remotely. I learned so much from that laptop. “./configure, make, make install” became muscle memory.
