Running strata with qwen3.8-flash-next keeps ~53G of model weights
resident, leaving little RAM for the desktop side and pushing ~13G of
anonymous pages into the 20G swapfile. With swap that full, a burst
risks OOM-killing processes. Disk space is not a constraint (1.9T
btrfs, ~1.4T free), so grow the swapfile to the classic 1x-RAM size.
Keep zram off and zswap at 10%: zram's compressed pool would steal page
cache that the mmap'd weights rely on.
Prefer the narrowest output of a dependency (for example stdenv.cc.cc.lib
instead of stdenv.cc.cc) and measure the built closure, since a full
toolchain can add hundreds of MiB. Also note how to check what is actually
needed (DT_NEEDED, exec'd tools) before trimming.
Disable the rootful system podman.socket on desktop hosts and drop the module's autoPrune, which prunes the rootful store and pulls in the rootful API service. Add a weekly per-user timer that prunes the rootless store instead.
Manage ~/.config/go-musicfox/config.toml declaratively: the upstream default plus the mpv engine, ~/Music download dir, 2 GiB cache and cover art.
The app rewrites the file with a temp file plus rename, which would replace a plain symlink, so use force = true like fcitx5's profile: the repo copy is restored on every rebuild and runtime edits are ephemeral. Runtime data and state stay on the persistent volume.
* feat(secrets): add work gitconfig secret, symlink it in home-manager
* feat(secrets): add a no-sudo replace recipe for new secrets
* refactor(secrets): move work gitconfig symlink into the desktop layer
* docs(skills): point nix-config-secrets at the private repo under ~/codes
Record where the private nix-secrets checkout lives and that agents should
do the mechanical secret work themselves, handing back only the
interactive/sudo agenix operations and pushes.
* docs(agents): add related repositories to nix-config
* chore(agents): adopt ~/src for source checkouts
Move third-party/source checkouts from ~/codes/src to ~/src so the home
layout reads as three siblings: ~/codes (personal), ~/work (work),
~/src (checkouts). Preserve and back up the new path, and update the
global rule and the two nixpkgs skill references.
* docs(agents): tighten the code layout rule
* docs(agents): fold the work-confidentiality note into the layout line
* docs(agents): base the confidentiality rule on repo visibility
* docs(agents): drop the stale KubeVirt mention
Catppuccin's home-manager module writes extra-substituters/extra-trusted-public-keys
for catppuccin.cachix.org into the user-level ~/.config/nix/nix.conf. Since the
normal user is no longer a trusted-user (modules/base/nix.nix), Nix ignores those
client-specified settings and warns on every command. The ports build locally, so
turn the user-level cache off instead.
nixvim has been disabled for a long time (programs.nixvim.enable = false), so
drop the flake input (and prune flake.lock). Port the settings it carried to
Home Manager's programs.neovim: opts and per-plugin setup become an initLua
block plus a plugin list. The catppuccin module already provides the
colorscheme, vi stays unmapped, and the plain system neovim package is
untouched so sudo/nvim --clean keep using it.
Allow clearly-implied task authorization, trust skills listed in the runtime's configured catalog, and restore the ban on following external-material instructions. Sync the affected evaluation scenarios.
* fix(youko): add ROCm OpenCL so Jellyfin can tone-map HDR
Jellyfin's HDR/DoVi transcodes use ffmpeg's `tonemap_opencl`, but only
Mesa was installed via `hardware.graphics.enable`, so no OpenCL ICD was
registered. ffmpeg then failed to create an OpenCL device ("Failed to
get number of OpenCL platforms: -1001") and aborted with exit code 237,
leaving HDR titles unplayable.
Add `rocmPackages.clr.icd` to `hardware.graphics.extraPackages`; it
ships the ICD for the Barceló iGPU (reported as `gfx90c`) under
/run/opengl-driver/etc/OpenCL/vendors, where `ocl-icd` (built with
`--enable-custom-vendordir`) finds it.
The Barceló iGPU only manages ~0.8x realtime for a 4K HDR -> 1080p
tone-mapped transcode, so playback can still buffer; this only makes
such titles playable at all.
* fix(youko): allow /dev/kfd so Jellyfin OpenCL can reach the GPU
The jellyfin module's `DeviceAllow` whitelist only permits the VA-API
render node (`/dev/dri/renderD128`). ROCm's OpenCL runtime opens
`/dev/kfd`, so even with the ICD installed OpenCL device creation failed
("No matching devices found") and HDR transcodes still aborted with exit
code 237.
Add `/dev/kfd rw` to the whitelist; list definitions merge with the
module's entry. Verified under the unit's sandbox (PrivateUsers,
PrivateTmp) that OpenCL init then succeeds as the jellyfin user.
conda/mitmproxy/wireshark are already Linux-gated in the shared home modules, and verible is unreferenced, so replacing them with emptyDirectory is unnecessary.
openldap's flaky tests are skipped upstream now (doCheck = true), so the override only forced local rebuilds of openldap/cyrus-sasl dependents such as libvirt and kio.
davfs2 caches the whole opened file regardless of cache_size, so opening media on /mnt/fileshare downloads it fully and blocks the mount. The share is no longer used.
