Repository files navigation

As used for my personal laptop.

• ZFS for all file-systems including the/ and the/boot, giving volumemanagement and snapshot backups.

• Mirror ZFS pools on dual (or more) SSDs, giving redundancy, fault tolerance,and high-performance striped reading.

• Mirror EFI system partitions, allowing booting from either in case one fails.

• Multiple swap partitions, one per drive, not mirrored, for high-performancestriped writing and reading.

• Script for reproducing the custom drive partitioning, ZFS layout, and NixOSinstallation.

• Very minimal system state, allowing entire installation to be more easilyreproduced.

• Organized so that per-machine configuration is separated from generalconfiguration.

• Multiple users for different activities, for better security and for tailoredenvironments.

• Companion repository thatprovides my "dot files" for users' home directories.

• Some non-trivial custom NixOS modules.

• Extra support for installing source-code and debug-info, according to yourchoice, for debugging of binaries (executables & libraries) installed by Nixpackages which don't normally provide this (for both pre-built w/o rebuildingor locally-built), and also for arbitrary binaries via dedicated temporarydirectories. Default installation of the source-code of the system's Glibcand Rust std libraries (w/o rebuilding any packages), to help when debuggingany of the many binaries using those. Options for NixOS to configure allthis.

These repositories were created using NixOS 21.05 and were minorly adjusted forall following release versions up to 24.11 which they now target.

• My approach was derived from that ofhttps://openzfs.github.io/openzfs-docs/Getting%20Started/NixOS/Root%20on%20ZFS.html,but uses a different ZFS dataset layout and a somewhat different partitionlayout.
