v0.4.69: PNG boot-menu background (iPXE built from source), NFS AUTH_SYS, FleetDM logo
Three things, headlined by the long-blocked graphical PXE menu.
## 1. Graphical PXE boot background — the iVentoy feature, finally
iVentoy paints a PNG background on the PXE screen using stock iPXE
built with CONSOLE_FRAMEBUFFER + IMAGE_PNG + CONSOLE_CMD; the public
iPXE binaries omit those, so `console --picture` is a no-op on them.
We now build our own iPXE from upstream with that thin config delta
(deploy/ipxe/local/{general,console}.h).
The 8-release blocker was cc1 segfaulting when an amd64 gcc ran under
QEMU emulation on the arm64 build host. Fix: a new `ipxe-build`
Dockerfile stage pinned to $BUILDPLATFORM (native arch — no emulation)
that cross-compiles x86_64 iPXE with CROSS_COMPILE=x86_64-linux-gnu-.
The compiler runs native and emits x86_64. Validated end-to-end:
png.o + fbcon.o + pixbuf.o all compile and link (confirmed via the
linked-ELF symbol table, not just strings), ~112s, no segfault. Host
tools needed libc6-dev (dropped by --no-install-recommends; without
it the native host compile falls through to iPXE's freestanding
headers and dies on bits/stdint.h — fixed).
Server side:
- pxe_logo.rs is now a full-screen background compositor: a dark field
(matching the WebUI theme) with the operator's uploaded logo across
the top, or — with no upload — a default OpenPXE rainbow disc drawn
with pure pixel math (no font/SVG deps). Always 1024x768 (iPXE
doesn't scale; this is the universal mode). WebP/JPEG/GIF/PNG in,
PNG out (iPXE only eats PNG).
- /branding/pxe-logo always returns a PNG now (default when no logo,
default when SVG) so the menu always has a background.
- render_menu uses `console --picture … --top 290 || console`: paints
the background and reserves the logo band on PNG-capable binaries
(x86_64 UEFI), cleanly falls back to text on the others. The ASCII
wordmark is GONE.
Only x86_64 UEFI is built from source (host-arch-agnostic cross build);
BIOS/i386/arm64 keep upstream-fetched no-PNG binaries + text fallback.
Modern clients are overwhelmingly x86_64 UEFI.
## 2. NFS AUTH_SYS credential — fixes NFS3ERR_ACCES
v0.4.68's privileged-port fix got past MNT3ERR_ACCES (mount); operators
then hit NFS3ERR_ACCES on READDIR because nfs3_client defaults to
AUTH_NONE and virtually every server exports sec=sys. We now present an
AUTH_UNIX credential (uid 0 / gid 0): no_root_squash servers treat us
as root, root_squash servers map us to anon which reads any
world-readable ISO share. Kept fixed (no UI knob) to stay dead-simple.
Hint updated: a remaining NFS3ERR_ACCES is now a server-side
permission/squash issue, not IP/auth-flavor.
## 3. FleetDM-style full-width logo (top-left)
When a custom logo is uploaded the sidebar header drops the bundled
mark + "OpenPXE" wordmark and lets the logo span the header
(left-aligned, capped 200x50, contain). Rendered server-side via a
brand-class in index_html (has_custom_logo) so there's no flash of the
default. The bundled-default case is unchanged.
Tests: 164 passing. clippy -D warnings clean. iPXE build stage
validated in isolation before the full image build.
