2 sourcesHave my server infrastructure on NixOS. Huge boost in productivity and stability, would never go back to standard linux. But man if something breaks it's a nuke going off. Sry for the long post, but thought I share my experience:
Mass storage on a big encrypted RaidZ array of spinning rust, no issues. Bootloader, /boot, Encrypted Root and Databases on Mirrored NVME Drives. And man is that a nailbiter on each update. Setup my drives during 22.11 following NixOS Root on ZFS instructions [1], which were amended following reports of systems becoming unbootable [2] and mostly removed later [3].
Besides initially being a broken setup [4] with an increasing amount of mounts each update stalling any system writes and causing updates to fail, it became a well running machine after that was fixed. Then during the 24.05 update and with no config cha
