Before mkinitcpio -P, a preset naming ALL_config="/etc/mkinitcpio.conf" is copied to the state's
taken-over/ and loses that line (another ALL_config is left and named); after it, an image without
kernel/x86/microcode/ in its first 64 KiB fails the unit and records nothing. The unit may write
/etc/mkinitcpio.d. The README names no node. Tests: 1977/AC7, 1977/AC8; AC3/AC4 fixtures write images.
Builds: L7, L8, L9 (issue 1977 note 4)
Replaces the state record read (root's 0700) with images_with_microcode per /boot/initramfs-*.img:
true when the first 64 KiB hold a path under kernel/x86/microcode/; an unreadable image goes to
image_errors with its error. Test: 1977/AC5.
Builds: L6 (issue 1977 note 3)
Declares amd-ucode and intel-ucode, the drop-in /etc/mkinitcpio.conf.d/mesh-microcode.conf, the
initramfs script and mesh-kernel-initramfs.service; kernel_boot answers the running revision and
whether the images were built with the drop-in. Tests: 1977/AC1-AC5.
Builds: L1, L2, L3, L4, L5 (issue 1977 note 2)
An image build node up 24 days had lost its running kernel's modules to a linux-lts upgrade, so tun
could not load and every RUN line failed in pasta. mesh-build-image now proves the tun device and,
whatever its look refuses, judges its node not eligible (capacity 0 with the reason), so the asks go
to a node that can build them. The kernel module loads tun at boot and declares kernel-modules-hook,
which keeps the running kernel's modules across an upgrade. Needs mesh-sdk fix/ace-tun (Puller.Eligible).
ADR 0508 §9 and §10: systemd-boot gets an entry from the booted command line, GRUB a regenerated menu only when its kernels change, a found kernel-copying hook is taken over, a full boot partition fails loudly.

A restart ran restore then apply, so every change passed back through the
found mode and rotated the journal again. Reload applies the new value
directly; restore also drops its state; no rotation while the machine boots;
the unit is sandboxed.
With THP 'always' journald's mmapped journal files sit in 2 MiB folios, so each small
journal write dirties and writes back 2 MiB; on the control node that saturated the
root mirror holding the bus store and the store, and the controller lost its lease.
The module sets the mode from a per-machine setting (default always, the kernel's own,
so assigning it changes nothing until a machine sets madvise), verifies it took, rotates
the journal once so new files are mapped under the new mode, gives back what it found
when stopped, and serves kernel_huge_pages to measure file_thp per unit.
