💻NixOS Simplifies Hibernate with Swap Partitions
NixOS makes hibernating easier with swap partitions
TL;DR
NixOS now simplifies hibernation by using swap partitions instead of files, making it easier to save system state to disk. This change is particularly beneficial for systems with SSDs, optimizing swappiness to 100.
NixOS has streamlined the hibernation process by using swap partitions instead of files, making it easier to save system state to disk. This change is particularly beneficial for systems with SSDs, optimizing swappiness to 100. Developers and system administrators can now enjoy a more straightforward hibernation process, reducing the complexity of managing swap files. The new configuration is simple and not long, and NixOS defaults to zstd compression, which offers the best compression ratio and is ideal for Nix builds.
Key Points
NixOS uses swap partitions for hibernation, simplifying the process.
Swappiness set to 100 works well for SSDs, optimizing system performance.
NixOS defaults to zstd compression, offering the best ratio for Nix builds.
Swap files can complicate hibernation, but partitions make it easier.
Config for using swap is simple, not long, and easy to implement.
Why It Matters
If you're running NixOS and need to hibernate your system, the new swap partition configuration simplifies the process. With swappiness set to 100, SSDs perform optimally. The default zstd compression ensures better memory management, fitting more pages into the compressed pool in memory.
