Option aliases/deprecations can now be declared in any NixOS module,
not just in nixos/modules/rename.nix. This is more modular (since it
allows for example grub-related aliases to be declared in the grub
module), and allows aliases outside of NixOS (e.g. in NixOps modules).
The syntax is a bit funky. Ideally we'd have something like:
options = {
foo.bar.newOption = mkOption { ... };
foo.bar.oldOption = mkAliasOption [ "foo" "bar" "newOption" ];
};
but that's not possible because options cannot define values in
*other* options - you need to have a "config" for that. So instead we
have functions that return a *module*: mkRemovedOptionModule,
mkRenamedOptionModule and mkAliasOptionModule. These can be used via
"imports", e.g.
imports = [
(mkAliasOptionModule [ "foo" "bar" "oldOption" ] [ "foo" "bar" "newOption" ]);
];
As an added bonus, deprecation warnings now show the file name of the
offending module.
Fixes#10385.
- systemd puts all into one output now (except for man),
because I wasn't able to fix all systemd/udev refernces
for NixOS to work well
- libudev is now by default *copied* into another path,
which is what most packages will use as build input :-)
- pkgs.udev = [ libudev.out libudev.dev ]; because there are too many
references that just put `udev` into build inputs (to rewrite them all),
also this made "${udev}/foo" fail at *evaluation* time
so it's easier to catch and change to something more specific
This way the binary gets stripped & rpath-shrinked etc. as usual.
We'd seem to get a runtime reference to gcc otherwise.
TODO: Maybe we should be able to set e.g. 'dontUnpack = true;'
to make this more pretty.
Adding the configuration option 'systemd.generators' to
specify systemd system-generators. The option allows to
either add new system-generators to systemd, or to over-
ride or disable the system-generators provided by systemd.
Internally, the configuration option 'systemd.generators'
maps onto the 'environment.etc' configuration option.
Having a convenience wrapper around 'environment.etc' helps
to group the systemd system-generator configuration more
easily with other 'systemd...' configurations.

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.

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.

With systemd 219, this is fine because systemd will cause the new
journald to re-use the file descriptors of the old one. So existing
connections to the journal are unaffected.

This reverts commit d170c98d13.
niksnut argues that we need smaller system closures, not bigger.
So users facing the trouble of getting gcc rebuilds after nix-collect-garbage
for any minimal nixos configuration change should use other means of
not losing the stdenv output.
One way is to keep one somewhere: nix-build -A stdenv -o stdenv '<nixpkgs>'.
Another may be to use nix.conf options like gc-keep-outputs, gc-keep-derivations
or env-keep-derivations.
This will help a lot on ARM, where nix-collect-garbage erases gcc; then, any
change to a small system config file requires rebuilding gcc again.
I don't know why it does not happen on x86. Maybe it just pulls the gcc from
hydra, if garbage is collected.
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).
Many bus clients get hopelessly confused when dbus-daemon is
restarted. So let's not do that.
Of course, this is not ideal either, because we end up stuck with a
possibly outdated dbus-daemon. But that issue will become irrelevant
in the glorious kdbus-based future.
Hopefully this also gets rid of systemd getting stuck after
dbus-daemon is restarted:

Since we restart all active target units (of which there are many),
it's hard to see the units that actually matter. So don't print that
we're starting target units that are already active.
‘nixos-rebuild dry-activate’ builds the new configuration and then
prints what systemd services would be stopped, restarted etc. if the
configuration were actually activated. This could be extended later to
show other activation actions (like uids being deleted).
To prevent confusion, ‘nixos-rebuild dry-run’ has been renamed to
‘nixos-rebuild dry-build’.
The PID 1 shell is executed as the last command in a sh invocation. Some
shells implicitly use exec for that, but the current busybox ash does not,
so the shell gets a wrong PID. Spell out the exec.
When gummiboot.timeout == null, the menu will still be skipped.
When gummiboot.timeout == 0, the menu will also be skipped.
The only way to show the menu 'indefinitely' is to show it a long time.
Now that dbus reload has been moved before restarting units,
the reload may fail if dbus has been stopped before.
The reload-or-restart will reload dbus if it's active,
otherwise start it.
During install, the bootloader script gets run inside a chroot after the
/etc/group bind-mount is unmounted. Since we're not doing any building,
this should be safe, but really nix should just not care if the group
does not exist when no build is needed.
