When using extlinux-conf-builder in a nix build using chroots, the
following error message could be seen:
/nix/store/XXX-extlinux-conf-builder.sh: line 121: cd: /nix/var/nix/profiles: No such file or directory
To avoid this, just skip the code path parsing /nix/var/nix/profiles
when $numGenerations (passed from the command line) is 0 (which is the
only legal value of $numGenerations in a nix build context).
Without a menu title, U-Boot's distro scripts just autoboot the first
entry by default.
When I initially wrote this, my board wasn't apparently running stock
U-Boot but had some local hacks saved in the U-Boot's environment
which made it always display the prompt.
When calling addEntry inside a subshell, the filesCopied array would
be updated only in the subshell's environment. This would only cause an
issue if no -g flag was passed to the script, causing no kernels
to be copied.
This fixes a failing assert in systemd-timesyncd (issue #5913) as it
expects the directory /run/systemd/netif/links/ to exist, and nothing in
NixOS currently creates it.
Also we get a net reduction in our code as rules for /run/utmp and
/var/log/journal are also provided by the same upstream file.

This shuts up this error from dbus:
May 11 13:52:16 machine dbus-daemon[259]: Unknown username "systemd-network" in message bus configuration file
May 11 13:52:16 machine dbus-daemon[259]: Unknown username "systemd-resolve" in message bus configuration file
which happens because the D-Bus config for networkd/resolved is
enabled unconditionally, and we don't have an easy way to turn it off.

Some filesystems like fat32 don't support symlinking and need to be
supported on /boot as an efi system partition. Instead of creating the symlink directly in boot, create the symlink in
a temporary directory which has to support symlinking.
This solves the problem that modprobe does not know about $MODULE_DIR
when run via sudo, and instead wrongly tries to read /lib/modules/:
$ sudo strace -efile modprobe foo |& grep modules
open("/lib/modules/3.14.37/modules.softdep", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
open("/lib/modules/3.14.37/modules.dep.bin", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
open("/lib/modules/3.14.37/modules.dep.bin", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
open("/lib/modules/3.14.37/modules.alias.bin", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
Without this patch, one would have to use sudo -E (preserves environment
vars). But that option is reserved for sudo users with extra rights
(SETENV), so it's not a solution.
environment.sessionVariables are set by PAM, so they are included in the
environment used by sudo.
This module generates a /boot/extlinux/extlinux.conf bootloader
configuration file that is supported by e.g. U-Boot:
http://git.denx.de/?p=u-boot.git;a=blob;f=doc/README.distro;hb=refs/heads/master
With this, all ARM boards supported by U-Boot can be booted in a common
way (a single boot file generator, all boards booting via initrd like
x86) and with same boot menu functionality as GRUB has.
-- sample extlinux.conf file --
# Generated file, all changes will be lost on nixos-rebuild!
# Change this to e.g. nixos-42 to temporarily boot to an older configuration.

It boots, but some things still don't work:
1) Installation of DTBs
2) Boot of initrd
Booting still needs a proper config.txt in /boot, which could probably be
managed by NixOS.
During the refactor of the networkd stuff in f8dbe5f, a lot of the
options are now needed by systemd.nix as well as networkd.nix but
weren't moved by that commit as well.
For now, this fixes all networkd VM tests except for the macvlan one and
thus it should fix#7505 for at least DHCP-based configuration.

In f8dbe5f, the default value for networking unit "enabled" option
suddenly flipped to false. I have no idea of whether this happened by
accident, but I'm setting it to true again, because it essentially
breaks systemd networking support and we have systemd.network.enable to
have a "turn the world off" switch.
And of course, because the mentioned commit obviously wasn't done with
even a run of the simplest run of one of the network VM tests, we now
get an evaluation error if we switch useNetworkd to true.
Fixes the core issue of #7505.

Otherwise, the enabled -> disabled transition won't be handled
correctly (switch-to-configuration currently assumes that if a unit is
running and exists, it should be restarted).
