The sysfs file /sys/kernel/mm/ksm/run seems to be available as soon as
the kernel has started, so no point in waiting for udev to "settle". If
for some reason it doesn't, we let the unit fail explicitly.
This is a very simple module that installs a single udev rule.
The rule set the ownership of all /dev/i2c-* devices to a
group, "i2c" by default but can be changed. The "uaccess" tag
also makes systemd add an ACL for users with a seat[1].

The `platform` field is pointless nesting: it's just stuff that happens
to be defined together, and that should be an implementation detail.
This instead makes `linux-kernel` and `gcc` top level fields in platform
configs. They join `rustc` there [all are optional], which was put there
and not in `platform` in anticipation of a change like this.
`linux-kernel.arch` in particular also becomes `linuxArch`, to match the
other `*Arch`es.
The next step after is this to combine the *specific* machines from
`lib.systems.platforms` with `lib.systems.examples`, keeping just the
"multiplatform" ones for defaulting.
Ports an OpenWRT patch for Atheros wireless drivers (ath*) which allows
the user to change the regulatory domain code to the one which actually
applies.
All Atheros devices have a regulatory domain burned into their EEPROM.
When using a device as AP, this domain is frequently overly restrictive
when compared to the regulation which applies in the country the device
actually operates in; often, this restriction disallows IR on all
channels making it impossible to use the device as an AP at all.
This commit introduces the NixOS config option
networking.wireless.athUserRegulatoryDomain which, if enabled, applies
the patch and sets the kernel config option ATH_USER_REGD.
The original OpenWRT patch targets Linux 5.8.
- This is fetched from a different URL, so allow passing that explicitly.
- There also isn't an nvidia-persistenced or nvidia-settings release for
this version, so use 450.57 instead. Also implement passing
persistenced and settings version explicitly.

Now allows applying external overlays either in form of
.dts file, literal dts context added to store or precompiled .dtbo.
If overlays are defined, kernel device-trees are compiled with '-@'
so the .dtb files contain symbols which we can reference in our
overlays.
Since `fdtoverlay` doesn't respect `/ compatible` by itself
we query compatible strings of both `dtb` and `dtbo(verlay)`
and apply only if latter is substring of the former.
Also adds support for filtering .dtb files (as there are now nearly 1k
dtbs).

Since systemd 243, docs were already steering users towards using
`journal`:
eedaf7f322
systemd 246 will go one step further, it shows warnings for these units
during bootup, and will [automatically convert these occurences to
`journal`](f3dc6af20f):
> [ 6.955976] systemd[1]: /nix/store/hwyfgbwg804vmr92fxc1vkmqfq2k9s17-unit-display-manager.service/display-manager.service:27: Standard output type syslog is obsolete, automatically updating to journal. Please update│······················
your unit file, and consider removing the setting altogether.
So there's no point of keeping `syslog` here, and it's probably a better
idea to just not set it, due to:
> This setting defaults to the value set with DefaultStandardOutput= in
> systemd-system.conf(5), which defaults to journal.
