Field report: even with CAP_SYS_ADMIN and full --privileged, NFS mounts
inside the OpenPXE container fail on Unraid with the same
"failed to apply fstab options" error v0.4.64 added diagnostics for.
The root cause is the host kernel: Unraid's base kernel ships without
the nfs/nfsv4 client modules loaded. Capabilities are necessary but
not sufficient; the modules have to be present on the host kernel for
in-container mount(2) to do anything. No container-side change can
fix that.
This is exactly the case every other PXE/imaging tool sidesteps
(Bootimus uses SMB; iVentoy, FOG, MAAS, Cobbler all rely on the host
to mount network storage and bind-mount the path into the imaging
service). v0.4.65 brings OpenPXE in line with that pattern.
What's new:
* `IsoSource::LocalDir { dir_id, relative_path }` — third source kind
alongside `Local` (uploaded) and `Nfs` (in-container mount).
* `LocalDirManager` (crates/iso-store/src/local_dir.rs) — registers
bind-mounted directories, validates them (absolute path, exists, is
a directory, readable), scans for *.iso files, registers them with
IsoStore. Persisted to <work_dir>/local_dirs.json so the relationship
survives restarts.
* `NfsHostCaps::detect()` — pure read of /proc/filesystems on startup.
Surfaced via GET /api/nfs/capabilities and used by the Storage tab to
show a prominent red banner above the NFS form when in-container
mounts cannot possibly work, pointing the operator at the Local
Directories card as the recommended path.
* Four new API routes:
GET /api/nfs/capabilities
GET /api/local-dirs
POST /api/local-dirs { path, label? }
DELETE /api/local-dirs/:id
POST /api/local-dirs/:id/scan
UI changes (crates/webui/src/app.js):
* Storage tab: new "Local directories" card under the NFS card with
the bind-mount form, an explainer paragraph (with the Docker
`-v /mnt/user/isos:/mnt/external-isos` command), and the list of
registered directories with rescan + remove actions.
* When NFS host caps are unavailable, the NFS card sprouts a red
banner explaining what's wrong and pointing at the local-dir
workaround. The card sub-header also flips to "N registered ·
recommended on this host".
* ISO table: new "dir:<id>" source badge; on-disk ISOs show "on disk"
in the actions column instead of a delete button (same pattern as
NFS — OpenPXE doesn't own those bytes).
* API reference table picks up the four new endpoints + a hint about
the new `port` field on NFS add.
Tests (+12, total 162):
* iso-store: 7 local_dir unit tests covering relative-path rejection,
missing path, non-directory file, empty-directory success, default
label, idempotent re-add, remove + iso-path-resolution clear.
* iso-store: 1 nfs unit test confirming NfsHostCaps::detect() never
panics and the boolean accessors are consistent.
* http-api: 4 integration tests covering /api/nfs/capabilities,
/api/local-dirs list/add/remove + relative-path 400.

VMware UEFI / Casper boot fix:
- Linux cmdline for Debian/Ubuntu/Mint/Pop!_OS/elementary now uses the
canonical Casper `iso-url=` option and `ds=nocloud`, matching the
fix Bootimus shipped in v0.1.67. The previous
`boot=casper netboot=url url=… ip=dhcp ---` form booted fine on
bare-metal UEFI but hung at "cloud-init running" on VMware guests
because subiquity / cloud-init can't reach a metadata datasource
through PXE.
Static binary (matches Bootimus v0.1.70):
- Dockerfile build stage now compiles against
x86_64-unknown-linux-musl. The resulting /openpxe has no glibc
dependency at all; the runtime stage still ships Debian slim for the
samba/wimtools/nfs-common shellouts, but a future scratch/distroless
variant is now a one-line swap. Cuts a class of "GLIBC_2.39 not
found" surprises on older RHEL/Rocky hosts.
Forms auth (Sonarr/Radarr-style):
- New AdminStore in openpxe-core: single admin record persisted to
<work_dir>/auth.json, bcrypt-hashed credentials, rotation requires
current password.
- New SessionStore in openpxe-http-api: in-memory UUID-keyed sessions
with 24h sliding TTL, openpxe_session HttpOnly cookie.
- Endpoints: POST /api/setup (first-run), POST /api/login, POST
/api/logout, GET /api/me, PUT /api/me/credentials (rotates and
revokes every other session).
- Auth middleware gates /api/* once the admin is configured;
passes through entirely until then (tests + fresh installs ride this
path). Allowlists PXE-essential paths (/boot.ipxe, /iso/*, /ipxe/*,
/api/queue/join, /api/queue/poll/*) so iPXE clients still work
without a cookie they can't send.
- WebUI: first-run setup card, login card, logout chip in the sidebar
footer, Account card in Settings for rotating creds. Auth screen is
fully styled (centered narrow card, matches Sonarr layout).
SSO config (FleetDM-shaped, storage-only):
- New SsoStore in openpxe-core: { enabled, idp_name, metadata,
metadata_url } persisted to <work_dir>/sso.json with size caps and
URL-scheme validation.
- Endpoints: GET /api/sso, PUT /api/sso. Validation: enabling SSO
without either metadata or metadata_url returns 400.
- WebUI: SSO card in Settings with a URL-vs-XML mode switch and an
inert "Sign in with X" button on the login screen while runtime
flow is pending. Per the brief: no Entity ID field (defaults to the
advertised public_base_url internally when SAML wiring lands).
Quality:
- 132 tests passing (was 106 in v0.4.4): +5 auth unit tests, +5 SSO
unit tests, +7 auth integration tests, +1 SSO integration test, +1
regression guard pinning the new Casper cmdline.
- cargo clippy --workspace --all-targets clean.

Settings:
- New top-level Settings tab. Carries a placeholder for the planned
LDAP / OIDC / user-management work, the new branding controls, and
the API reference at the bottom.
- Custom logo upload (PNG/SVG/JPEG/WebP/GIF up to 2 MB) replaces the
bundled brand mark via /assets/logo.svg; bytes live at
<work_dir>/branding/ and survive restart. The original "OpenPXE
v<x.y.z>" pins to the sidebar footer for support.
- API reference rendered from a new GET /api/docs into a per-method
coloured pill list grouped by area.
ISO category (Storage):
- New IsoCategory { Os, Tools } on IsoMeta with PUT
/api/isos/:id/category. Storage table's Type cell becomes a
dropdown; selecting Tools moves the ISO into the Tools submenu next
to memtest / shell / NIC info and removes it from the OS Installers
family submenu. Family detection still drives BIOS/UEFI / kernel
args; only the menu placement changes.
Storage telemetry:
- New IsoStore::disk_usage (libc::statvfs, lives in iso-store so the
http-api crate stays #![forbid(unsafe_code)]) and GET
/api/storage/disk. The Storage tab now shows free/used/total for
the volume hosting the ISO directory with an 80%/95% colour ramp.
UI polish:
- Brand block in the sidebar now matches the topbar height exactly,
so the divider runs straight across the top of the app rather than
stepping; version label moved out of the brand and pinned to the
sidebar footer ("OpenPXE v0.4.4").
- Light-mode terminal: --terminal-bg + per-level text colours track
the active theme rather than being hard-coded dark.
- About: lead paragraph spans the full content width; new Docs row
links to https://openpxe.com/.
106 tests passing (was 89 in v0.4.1, +17 across branding unit tests
and new integration coverage for category / disk / docs / branding).

Add browser-safe chunked ISO uploads with progress, partial-file visibility, offset validation, and abort cleanup while keeping the legacy multipart endpoint for API clients.
Record host-log validation coverage, keep the queue/status UI copy clean, move release docs to 0.4.1, and tighten the dark theme to a near-black Netbox-style palette.
- Upload reliability + diagnostics:
- api_upload_iso now distinguishes clean EOF from mid-stream errors;
a truncated multipart body (proxy buffer cap, network drop) returns
400 with the cause and a "try the LAN IP" hint instead of silently
finalising a partial file.
- Per-stage tracing (begin/MB-watermark/finish/abort) so a stuck
upload is debuggable from the Terminal tab.
- Web upload UI surfaces bytes/total, percent, throughput, ETA, and
maps 413/502/504/network-drop to actionable hints.
- New BootLog feature under Hosts:
- openpxe-core::BootLog — bounded in-memory ring (500) + append-only
JSONL on disk, recording (timestamp, mac, ip, target_id,
target_title) every time a boot entry script is served.
- iPXE per-entry chain URLs grow ?mac=${mac}; password prompt
submission carries it through; host-binding short-circuit uses the
bound MAC. ConnectInfo<SocketAddr> wired for peer IP capture (with
optional fallback so tower::oneshot in tests still works).
- GET /api/boot-log endpoint + Host log table under the Hosts tab.
- UI changes:
- Queue card header "Forge" → "Status".
- Removed Tinkerbell attribution sentence from Hosts tab.
- Topbar readiness chip moved into the sidebar footer as
"Service status: Ready / Advertised to clients / <url>", grouping
advertised PXE URL with operator-relevant status.
- Jet-black dark palette (#000 / #0a0a0a / #141414 / #1c1c1c)
replacing the blue-tinted ramp; terminal toolbar/input recoloured
to match.
- 89 tests passing (was 85 in v0.3.2); cargo clippy --workspace
--all-targets clean.
