42709fb4e9 switch-to-configuration: Handle failure to read /proc/1/exe
It's not entirely clear why this happens, but sometimes /proc/1/exe
returns a bogus value, like
/ar3a3j6b9livhy5fcfv69izslhgk4gcz-systemd-217/lib/systemd/systemd. In
any case, we can just conservatively assume that we need to restart
systemd when this happens.

Fixes #10261.

119c8f91e7 nixos: introduce system.nixosLabel option and use it where appropriate
Setting nixosVersion to something custom is useful for meaningful GRUB
menus and /nix/store paths, but actuallly changing it rebulids the
whole system path (because of `nixos-version` script and manual
pages). Also, changing it is not a particularly good idea because you
can then be differentitated from other NixOS users by a lot of
programs that read /etc/os-release.

This patch introduces an alternative option that does all you want
from nixosVersion, but rebuilds only the very top system level and
/etc while using your label in the names of system /nix/store paths,
GRUB and other boot loaders' menus, getty greetings and so on.

switch-to-configuration: Fix unit name quoting.
Clearly it would be the best if we'd directly generate mount units
instead of converting /etc/fstab. But in order to do that we need to
test it throughly so this approach is for the next stable release.

This fix however is intended for inclusion into release-14.12 and
release-15.09.

Using a simple regular expression unfortunately isn't sufficient for
proper mount unit name quoting/escaping and there is a utility in
systemd called systemd-escape which does nothing less than that.

Of course, using an external program to escape the unit name is way more
expensive and causes us to fork for each mount point.

But given that we already do quite a lot of forks just for unit starting
and stopping, I think it doesn't matter that much. Well, except if you
have a whole bunch of mount points.

However, if the latter is the case and you have thousands of mount
points, you probably have stumbled over this already if your mount point
contains a dash.

As for my motivation to fix this: I've stumbled on this while trying to
fix the "none" backend test for NixOps (see NixOS/nixops#350), where the
target machines use /nix/.ro-store and /nix/.rw-store as mount points.

The implementation we had so far did improperly escape it so those mount
points got the following unit files:

 * nix-.ro-store.mount
 * nix-.rw-store.mount

The correct names for these units are however:

 * nix-.ro\x2dstore.mount
 * nix-.rw\x2dstore.mount

So using systemd-escape now properly generates these names.

5d02c02a9b systemd: Use upstream tmpfiles.d rules
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.

1c39a47ac8 Reload, don't restart, dbus.service
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:

it's hard to see the units that actually matter. So don't print that

a574065a81 nixos-rebuild: Add ‘dry-activate’ command
‘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’.

2beb43174f nixos-rebuild: use reload-or-restart for dbus. Closes #5767
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.

179acfb664 Allow upstream systemd units to be extended
If you define a unit, and either systemd or a package in
systemd.packages already provides that unit, then we now generate a
file /etc/systemd/system/<unit>.d/overrides.conf. This makes it
possible to use upstream units, while allowing them to be customised
from the NixOS configuration. For instance, the module nix-daemon.nix
now uses the units provided by the Nix package. And all unit
definitions that duplicated upstream systemd units are finally gone.

This makes the baseUnit option unnecessary, so I've removed it.

29027fd1e1 Rewrite ‘with pkgs.lib’ -> ‘with lib’
Using pkgs.lib on the spine of module evaluation is problematic
because the pkgs argument depends on the result of module
evaluation. To prevent an infinite recursion, pkgs and some of the
modules are evaluated twice, which is inefficient. Using ‘with lib’
prevents this problem.

0d18d39e98 switch-to-configuration.pl: Handle successful auto-restarts
switch-to-configuration.pl is currently hard-coded to assume that if a
unit is in the "auto-restart" state that something has gone wrong, but
this is not strictly true. For example, I run offlineimap as a oneshot
service restarting itself every minute (on success). NixOS currently
thinks that offlineimap has failed to start as it enters the
auto-restart state, because it doesn't consider why the unit failed.

This commit changes switch-to-configuration.pl to inspect the full
status of a unit in auto-restart state, and now only considers it failed
if the ExecMainStatus is non-zero.
