vasilito f31522130f fix: comprehensive boot warnings and exceptions — fixable silenced, unfixable diagnosed
Build system (5 gaps hardened):
- COOKBOOK_OFFLINE defaults to true (fork-mode)
- normalize_patch handles diff -ruN format
- New 'repo validate-patches' command (25/25 relibc patches)
- 14 patched Qt/Wayland/display recipes added to protected list
- relibc archive regenerated with current patch chain

Boot fixes (fixable):
- Full ISO EFI partition: 16 MiB → 1 MiB (matches mini, BIOS hardcoded 2 MiB offset)
- D-Bus system bus: absolute /usr/bin/dbus-daemon path (was skipped)
- redbear-sessiond: absolute /usr/bin/redbear-sessiond path (was skipped)
- daemon framework: silenced spurious INIT_NOTIFY warnings for oneshot_async services (P0-daemon-silence-init-notify.patch)
- udev-shim: demoted INIT_NOTIFY warning to INFO (expected for oneshot_async)
- relibc: comprehensive named semaphores (sem_open/close/unlink) replacing upstream todo!() stubs
- greeterd: Wayland socket timeout 15s → 30s (compositor DRM wait)
- greeter-ui: built and linked (header guard unification, sem_compat stubs removed)
- mc: un-ignored in both configs, fixed glib/libiconv/pcre2 transitive deps
- greeter config: removed stale keymapd dependency from display/greeter services
- prefix toolchain: relibc headers synced, _RELIBC_STDLIB_H guard unified

Unfixable (diagnosed, upstream):
- i2c-hidd: abort on no-I2C-hardware (QEMU) — process::exit → relibc abort
- kded6/greeter-ui: page fault 0x8 — Qt library null deref
- Thread panics fd != -1 — Rust std library on Redox
- DHCP timeout / eth0 MAC — QEMU user-mode networking
- hwrngd/thermald — no hardware RNG/thermal in VM
- live preload allocation — BIOS memory fragmentation, continues on demand

<refsect1 id='description'><title>DESCRIPTION</title>
<para>The <command>dbus-monitor</command> command is used to monitor messages going
through a D-Bus message bus. See
<ulink url='https://www.freedesktop.org/wiki/Software/dbus/'>https://www.freedesktop.org/wiki/Software/dbus/</ulink> for more information about
the big picture.</para>
<para>There are two well-known message buses: the systemwide message bus
(installed on many systems as the "messagebus" service) and the
per-user-login-session message bus (started each time a user logs in).
The --system and --session options direct <command>dbus-monitor</command> to
monitor the system or session buses respectively. If neither is
specified, <command>dbus-monitor</command> monitors the session bus.</para>
<para><command>dbus-monitor</command> has two different text output
modes: the 'classic'-style
monitoring mode, and profiling mode. The profiling format is a compact
format with a single line per message and microsecond-resolution timing
information. The --profile and --monitor options select the profiling
and monitoring output format respectively.</para>
<para><command>dbus-monitor</command> also has two binary output modes.
The binary mode, selected by <literal>--binary</literal>, outputs the
entire binary message stream (without the initial authentication handshake).
The PCAP mode, selected by <literal>--pcap</literal>, adds a
PCAP file header to the beginning of the output, and prepends a PCAP
message header to each message; this produces a binary file that can
be read by, for instance, Wireshark.</para>
<para>If no mode is specified,
<command>dbus-monitor</command> uses the monitoring output format.</para>
<para>In order to get <command>dbus-monitor</command> to see the messages you are interested
in, you should specify a set of watch expressions as you would expect to
be passed to the <emphasis remap='I'>dbus_bus_add_match</emphasis> function.</para>
<para>The message bus configuration may keep <command>dbus-monitor</command> from seeing
all messages, especially if you run the monitor as a non-root user.</para>
