NixOS System Updates and Configuration Changes

been renamed from `ps3netsrv++` to `ps3netsrv` and cli parameters have changed. - `ssm-agent` package and module were renamed to `amazon-ssm-agent` to be consistent with the upstream package name. - `services.kea.{ctrl-agent,dhcp-ddns,dhcp,dhcp6}` now use separate runtime directories instead of `/run/kea` to work around the runtime directory being cleared on service start. - `mkDerivation` rejects MD5 hashes now. - The `junicode` font package has been updated to [major v2](https://github.com/psb1558/Junicode-font/releases/tag/v2.001), which is a font family now. In particular, plain `Junicode.ttf` no longer exists. In addition, TrueType font files are now placed in `font/truetype` instead of `font/junicode-ttf`; this change does not affect use via `fonts.packages` option. - The `prayer` package as well as `services.prayer` have been removed because it's been unmaintained for several years and the author's website has vanished. - The `chrony` NixOS module now tracks the real-time clock drift from the system clock with `rtcfile` and automatically adjusts it with `rtcautotrim` when it exceeds the maximum error specified in `services.chrony.autotrimThreshold` (defaults to 30 seconds). If you enabled `rtcsync` in `extraConfig`, you should remove RTC related options from `extraConfig`. If you do not want chrony configured to keep the RTC in check, you can set `services.chrony.enableRTCTrimming = false;`. - `trilium-desktop` and `trilium-server` have been updated to [v0.61](https://github.com/zadam/trilium/releases/tag/v0.61.12). For existing installations, upgrading to this version is supported only after running v0.60.x at least once. If you are still on an older version, make sure to update to v0.60 (available in NixOS 23.05) first and only then to v0.61 (available in NixOS 23.11). - Cassandra now defaults to v4.x, updated from v3.11.x. - FoundationDB now defaults to major version 7. - [glibc](https://www.gnu.org/software/libc/) has been updated from v2.37 to v2.38. Refer to the [the release notes](https://sourceware.org/glibc/wiki/Release/2.38) for more details. - `linuxPackages_testing_bcachefs` is now soft-deprecated by `linuxPackages_testing`. - Please consider changing your NixOS configuration's `boot.kernelPackages` to `linuxPackages_testing` until a stable kernel with bcachefs support is released. - PostgreSQL now defaults to major version 15. - All [ROCm](https://rocm.docs.amd.com/en/latest/) packages have been updated to v5.7.0. - [ROCm](https://rocm.docs.amd.com/en/latest/) package attribute sets are versioned: `rocmPackages` -> `rocmPackages_5`. - [systemd](https://systemd.io) has been updated from v253 to v254, refer to [the release notes](https://github.com/systemd/systemd/blob/v254/NEWS#L3-L659) for more details. - `boot.resumeDevice` **must be specified** when hibernating if not in EFI mode. - systemd may warn your system about the permissions of your ESP partition (often `/boot`), this warning can be ignored for now, we are looking into a satisfying solution regarding this problem. - Updating with `nixos-rebuild boot` and rebooting is recommended, since in some rare cases the `nixos-rebuild switch` into the new generation on a live system might fail due to missing mount units. - If the user has a custom shell enabled via `users.users.${USERNAME}.shell = ${CUSTOMSHELL}`, the assertion will require them to also set `programs.${CUSTOMSHELL}.enable = true`. This is generally safe behavior, but for anyone needing to opt out from the check `users.users.${USERNAME}.ignoreShellProgramCheck = true` will do the job. - `yarn-berry` has been updated to v4.0.1. This means that NodeJS versions less v18.12 are no longer supported by it. Refer to the [upstream changelog](https://github.com/yarnpkg/berry/blob/master/CHANGELOG.md) for more details. - GNOME has been updated to v45. Refer to the [release

This document details significant updates, renames, removals, and configuration adjustments within NixOS. Major component updates include Cassandra (now v4.x), FoundationDB (v7), glibc (v2.38), PostgreSQL (v15), ROCm (v5.7.0 with versioned attribute sets), systemd (v254), trilium-desktop/server (v0.61, requiring a phased upgrade path), yarn-berry (v4.0.1, requiring NodeJS >= v18.12), and GNOME (v45). Packages such as `ps3netsrv` and `ssm-agent` were renamed, while `prayer` was removed. Configuration changes involve `services.kea` using separate runtime directories, and the `chrony` module now automatically manages RTC drift. `mkDerivation` now rejects MD5 hashes. Key breaking changes include `systemd` requiring `boot.resumeDevice` for non-EFI hibernation and a new requirement for custom shell users to explicitly enable their shell program. The `junicode` font package received a major update affecting filenames and paths, and `linuxPackages_testing_bcachefs` is soft-deprecated.
