According to the MySQL manual, this is a perfectly legal way of
shutting down the server. The shutdown logs also looks fine:

This is a rather large commit that switches user/group creation from using
useradd/groupadd on activation to just generating the contents of /etc/passwd
and /etc/group, and then on activation merging the generated files with the
files that exist in the system. This makes the user activation process much
cleaner, in my opinion.
The users.extraUsers.<user>.uid and users.extraGroups.<group>.gid must all be
properly defined (if <user>.createUser is true, which it is by default). My
pull request adds a lot of uids/gids to config.ids to solve this problem for
existing nixos services, but there might be configurations that break because
this change. However, this will be discovered during the build.
Option changes introduced by this commit:
* Remove the options <user>.isSystemUser and <user>.isAlias since
they don't make sense when generating /etc/passwd statically.
* Add <group>.members as a complement to <user>.extraGroups.
* Add <user>.passwordFile for setting a user's password from an encrypted
(shadow-style) file.
* Add users.mutableUsers which is true by default. This means you can keep
managing your users as previously, by using useradd/groupadd manually. This is
accomplished by merging the generated passwd/group file with the existing files
in /etc on system activation. The merging of the files is simplistic. It just
looks at the user/group names. If a user/group exists both on the system and
in the generated files, the system entry will be kept un-changed and the
generated entries will be ignored. The merging itself is performed with the
help of vipw/vigr to properly lock the account files during edit.
If mutableUsers is set to false, the generated passwd and group files will not
be merged with the system files on activation. Instead they will simply replace
the system files, and overwrite any changes done on the running system. The
same logic holds for user password, if the <user>.password or
<user>.passwordFile options are used. If mutableUsers is false, password will
simply be replaced on activation. If true, the initial user passwords will be
set according to the configuration, but existing passwords will not be touched.
I have tested this on a couple of different systems and it seems to work fine
so far. If you think this is a good idea, please test it. This way of adding
local users has been discussed in issue #103 (and this commit solves that
issue).
This adds nix-run, which is a thin wrapper around nix-build.
nix-run calls nix-build, and then executes the resulting build.
If no executable artifact is built, nix-runs outputs an error
message.
myEnvRun calls myEnvFun and builds a script that directly runs
the load-env-* script.
Together, nix-run and myEnvRun allows you to set up an environment
that can be loaded in this way:
envs.nix:
{
gcc = myEnvRun {
name = "gcc";
buildInputs = [ gcc ];
};
}
$ nix-run -A gcc envs.nix
You end up directly in your environment without having to do
nix-env -i. You will always have a fresh environment and you
don't have to pollute you profile with a lot of env packages.
Rename NetworkManager-dispatcher.service to
dbus-org.freedesktop.nm-dispatcher.service so it is found by systemd (NixOS
doesn't handle the Alias directive in the unit file)
If the option is enabled, the DNS servers from networking.nameservers
will be inserted in /etc/resolv.conf after the DNS servers that
NetworkManager receieves by DHCP, or that is configured manually
in the connection settings.
If the option is enabled, the DNS servers from networking.nameservers
will be inserted in /etc/resolv.con and override any DNS servers that
NetworkManager receieves by DHCP, or that is configured manually
in the connection settings.
For Linux, the phases was run in the wrong order. I've
fixed that, but the package is still a complete mess that
needs to be cleaned up. The linux and darwin builds should
probably be separated into two different Nix expressions
to avoid the current conditional mess.
I also added a patch that makes dovecot search for
plugins in /var/lib/dovecot/modules. This way, you
can add plugins from several packages without running
into circular dependencies. The module dir needs to
be populated before the dovecot service is started,
for example. This is currently not done in NixOS, so
you need to implement your own service in order to
get the plugins working.
The module patch has not been added to the old 2.1.x
package.
