* acquire DHCP on the interfaces with networking.interface.$name.useDHCP == true or on all interfaces if networking.useDHCP == true (was only only "eth0")
* respect "mtu" if it was in DHCP answer (it happens in the wild)
* acquire and set up staticroutes (unlike others clients, udhcpc does not do the query by default); this supersedes https://github.com/NixOS/nixpkgs/pull/41829
The isKexecable flag treated Linux without kexec as just a normal
variant, when it really should be treated as a special case incurring
complexity debt to support.
Resolved the following conflicts (by carefully applying patches from the both
branches since the fork point):
pkgs/development/libraries/epoxy/default.nix
pkgs/development/libraries/gtk+/3.x.nix
pkgs/development/python-modules/asgiref/default.nix
pkgs/development/python-modules/daphne/default.nix
pkgs/os-specific/linux/systemd/default.nix
This can be used to fix issues where udhcpc times out before
acquiring a lease. For example of these issues, see:

At one point in my configuration I had:
boot.kernel.sysctl = {
# https://unix.stackexchange.com/questions/13019/description-of-kernel-printk-values
"kernel.printk" = "4 4 1 7";
};
which triggered:
error: The unique option `boot.kernel.sysctl.kernel.printk' is defined multiple times, in `/home/teto/dotfiles/nixpkgs/mptcp-unstable.nix' and `/home/teto/nixpkgs/nixos/modules/system/boot/kernel.nix'.

This simple addition allows to override it.
