I have NixOS running on my main desktop with some unusual changes:
- / is mounted as tmpfs, with /etc, /nix and /var being mounted from the actual system partition (this actually isn't too uncommon on NixOS)
- For swap, zswap and dynamically allocated swapfiles using swapspace daemon (this is imo the best swap setup if you don't need hibernation)
- Akonadi (KDE's PIM server) using PostgreSQL instead of MySQL
- ISO8601 date format, for this I have glibc's en_DK locale which does this copied to en_SE because Qt has en_SE as the locale with ISO date
- A couple changes to make the layout more like macOS because I can:
- Partitions are either mounted or auto-symlinked (if they can't be mounted there, such as for the system partition) under /Volumes
- I patched udisks to also mount devices under /Volumes
- User home directories are under /Users and root's home is /var/root
- Keyboard layout changed as far as I can to be mostly like Mac's so I don't have to rethink layouts as much when switching between this and my MacBook
- Can't technically list this anymore since I've had to tear it down for unrelated reasons but NFS using Kerberos authentication for my NAS
- This is apparently very unusual since a lot of games completely break with it but two monitors with the main monitor on the right
