Good: this means it's not hanging holding the s6 dataase lock.
Bad: it's the ugliest implementation and doesn't deserve to be preserved
(tbf the ugliness is not new)
We call s6-rc -u -p default to restart/start the base services
on a rebuild, otherwise services that are only in the new
configuration won't come up. However, this stops any service
started by a trigger. So, workaround is to restart the trigger
service and expect it to restart the services it manages if they're
needed
this is like pkgs.callService except that it passes
config.system.service as a param so that the service
being defined can invoke other services
if this proves to be a good idea, all uses of
pkgs.callService should be changed to use it instead
a firewall with no configuration will get a relatively sane ruleset. a
firewall with `extraRules` will get them deep merged into the default
rules. Specifying `rules` will override the defaults
config.boot.commandLineDtbNode can be set from `bootargs` to
`bootargs-override` (used for boards where the u-boot on the board does
set `bootargs` on its own).
In that case, the code updating the cmdline for tftpboot purposes also
needs to update this node, not the `bootargs` node.
Otherwise the kernel won't find the phram device, as it never heard
about it, as it didn't get the necessary cmdline options.
this is a bit of an experiment to reduce the copy-paste in
examples by turning them into "application" modules.
planning to follow up with another module for "wifi router"
This adds a simple boot blessing module, to be used, with the Zyxel NWA50AX.
There's a lot of elephant in the rooms: how do you upgrade kernel, etc.

Zyxel "firmware" format is just… a FIT with some metadata on the models.
This FIT is like this:
--------------------------
uImage FIT header
--------------------------
Linux kernel
--------------------------
FDT DTB
--------------------------
Padding so that
this makes
8192kb [1]
--------------------------
UBI volume
as a root filesystem
--------------------------
We just reproduce this in a very brutal and naive way.
In the future, this seems worth to generalize and modularize this idea
so that zyxel-nwa-fit is just an instance of a more general output.

I believe there should be another module exposing `rootubifs` as `rootfs`
or let any other module just subsume that component like `zyxel-nwa-fit` output.

Some devices have a U-boot variant that does not accept a third
parameter on the "bootm" command, meaning we can't override the dtb
in the bootloader so have to smush it back into the kernel image
This doesn't work in QEMU but I think the problem is with the
U-Boot configuration for QEMU. It does work on at least one
hardware device so I'm pushing it anyway
