For security reasons, and generally, it is best to create a more fine
grained group than plugdev. This way users that wish to tweak razer
devices don't have access to the entire plugdev group's permissions.
This is of course a breaking change.
use it when networkmanager or wpa_supplicant is enabled.

Note that all kernels on unstable are newer that 4.15, which is required
for this to work.
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.
