Alertmanager 0.13.0 doesn't support single dash long options, so '-config.file'
for example is parsed as '-c', which leads to the service not starting.
Previously the parameters were just dropped. Now they can be read
from within the handler script. An example to show this is added.
Makes use of the new writeShellScript function as suggested in:
issue #21557
resolves: #21557
Inspired from the dhcpd service implementation
Only 2 configurations options at the moment:
- enabled
- path to config directory (defaults to /etc/raddb)
Implementation was also inspired from ArchLinux
systemd file and corrected with @dotlambda and
@fpletz help.
If you have more than 1 User with hasedPassword Option set it generates
```
rm -f /var/lib/mosquitto/passwd
touch /var/lib/mosquitto/passwd
echo 'user1:$6$xxx' > /var/lib/mosquitto/passwd
echo 'user2:$6$xxx' > /var/lib/mosquitto/passwd
```
Which ends up in only having 1 user.
Of course, you'll get a bunch of warnings from the activation script:

l2tp saves its secrets into /etc/ipsec.d but strongswan would not read
them. l2tp checks for /etc/ipsec.secrets includes /etc/ipsec.d and if
not tries to write into it.
Solution:
Have the strongswan module create /etc/ipsec.d and /etc/ipsec.secrets
when networkmanager_l2tp is installed.
Include /etc/ipsec.secrets in
/nix/store/hash-strongswan/etc/ipsec.secrets so that it can find l2tp
secrets.
Also when the ppp 'nopeerdns' option is used, the DNS resolver tries to
write into an alternate file /etc/ppp/resolv.conf. This fails when
/etc/ppp does not exist so the module creates it by default.
The use of Nix 2.0 significantly simplifies the installer, since we
can just pass a different store URI (--store /mnt) - it's no longer
needed to set up a chroot environment for the build, and to bootstrap
Nix into the chroot.
Also, commands that need to run in the installation (namely boot
loader installation and setting a root password) are now executed
using nixos-enter.
This also removes the need for nixos-prepare-root since any required
initialisation is done by Nix or by the activation script.
* The environment variables NIX_CONF_DIR, NIX_BUILD_HOOK and
NIX_REMOTE are no longer needed.
* A /bin/sh (from busybox) is provided by default in sandboxes.
* Various options were renamed.
Among other things, this will allow *2nix tools to output plain data
while still being composable with the traditional
callPackage/.override interfaces.
This can be disabled with the `withKerberos` flag if desired.
Make the relevant assertions lazy,
so that if an overlay is used to set kerberos to null,
a later override can explicitly set `withKerberos` to false.
Don't build with GSSAPI by default;
the patchset is large and a bit hairy,
and it is reasonable to follow upstream who has not merged it
in not enabling it by default.

`nixos-generate-config` detects the `cpuFreqGovernor` suited best for my
machine, e.g. `powerManagement.cpuFreqGovernor = lib.mkDefault "powersave";`.
However the `powerManagement` module sets a sensitive default for
`cpuFreqGovernor` using `mkDefault` to avoid breackage with older
setups. Since 140ac2f1 the `hardware-configuration.nix` sets the
gorvernor with `mkDefault` as well which causes evaluation errors if the
powermanagement module is enabled:
```
error: The unique option `powerManagement.cpuFreqGovernor' is defined multiple times, in `/home/ma27/Projects/nixos-config/hardware-configuration.nix' and `/nix/var/nix/profiles/per-user/root/channels/nixos/nixpkgs/nixos/modules/config/power-management.nix'.
```
Using `mkOptionDefault` rather than `mkDefault` in the powermanagement
module fixes this issue as it decreases the priority of the module and
prefers the value set in `hardware-configuration.nix`.
I have confirmed the change using the following VM declaration:
```
{
cpuFreq = { lib, ... }: {
powerManagement.cpuFreqGovernor = lib.mkDefault "powersave";
powerManagement.enable = true;
};
}
```
`services.postfix.config` is now correctly merged with the default attrset
specified in the module. Some options that are lists in postfix also
have to be lists in nix to be merged correctly. Other default options are
now set with `mkDefault` so they can be overridden via the module system.
- Add a new parameter `imageType` that can specify either "efi" or
"legacy" (the default which should see no change in behaviour by
this patch).
- EFI images get a GPT partition table (instead of msdos) with a
mandatory ESP partition (so we add an assert that `partitioned`
is true).
- Use the partx tool from util-linux to determine exact start + size
of the root partition. This is required because GPT stores a secondary
partition table at the end of the disk, so we can't just have
mkfs.ext4 create the filesystem until the end of the disk.
- (Unrelated to any EFI changes) Since we're depending on the
`-E offset=X` option to mkfs which is only supported by e2fsprogs,
disallow any attempts of creating partitioned disk images where
the root filesystem is not ext4.
The default cache directory set by oh-my-zsh is $ohMyZsh/cache which
lives in the Nix store in our case. This causes issues with several
completion plugins provided by oh-my-zsh.
This was only applicable to very specific hardware, and the only person
with an apparent interest in maintaining it (me) no longer uses the
hardware in question.
When a domain has a lot of subdomains, it is quite easy to hit the rate limit:
https://letsencrypt.org/docs/rate-limits/
Instead you can define the certificate manually in `security.acme.certs` and list the subdomains in the `extraDomains` option.
sg and newgrp only changes the current user session and should be
available to users even if the "users.mutableUsers" option is set.
These are common, useful commands.
chfn does modify the /etc/passwd GECOS field which is also controlled
by the option "users.users.<name?>.description", so it's less
appropriate to make it available when "users.mutableUsers" is set.
However, because CHFN_RESTRICT in login.defs is never set in current
NixOS the chfn functionality is never available to users anyway and
may as well have its SUID disabled, as only root is able to use it.
This is recommended in the chfn man page in this case.
This makes memoization of Nixpkgs evaluation less effective, since
some Nixpkgs invocations may have 'config = {}' while others may have
'config = { xorg = {}; }'.
Instead set 'config = {}'.
This reverts commit 45c5a915980fbe1fa6f0ff80ab2d11b60b844d9e.
This breaks PredictableNetworkInterfaceNames on systems without networkd.
We should only include this file from systemd, when networkd is enabled.
in read-only way. If the cache directory is empty and you use the
very same service for system's DNS, kresd is unable to bootstrap root
trust anchors, as it would need a DNS lookup.
Also, if we don't rely on bootstrap, the extra lua deps of kresd could
be dropped by default, but let's not do that now, as the difference in
closure size is only ~4 MB, and there may be other use cases than
running the package as nixos service this way.
mate-control-center depends on mate-settings-daemon, but the later needs
gsettings schemas provided by the former. To fix this the gsettings schema
path from mate-control-center is added to XDG_DATA_DIRS at session
startup.
Udev changed its internal naming, so this rule file no longer applied correctly.
Therefore some properties such as network driver no longer matched in
systemd-networkd.
After updating we have more properties in systemd-networkd:
$ sudo networkctl status wlp3s0
...
Driver: iwlwifi
...
To prevent this in future, the file is no copied from systemd directly
The unnecessary dependency of sockets.target on kresd.service causes a
dependency cycle preventing kresd.service from starting at boot:
sockets.target -> kresd.service -> basic.target -> sockets.target
This allows to configure additional configuration files for Synapse. This way
secrets can be kept in a secure place on the file system without a need to go
through the Nix store.
To make the configuration of `yabar` more pleasant and easier to
validate, a NixOS module will be quite helpful.
An example config could look like this:
```
{
programs.yabar = {
enable = true;
bars.top.indicators.exec = "YA_DATE";
};
}
```
The module adds a user-controlled systemd service which runs `yabar` after
starting up X.
before:
- /var/run/memcached is a bad default for a socket path, since its
parent directory must be writeable by memcached.
- Socket directory was not created by the module itself -> this was
left as a burden to the user?
- Having a static uid with a dynamic user name is not very useful.
after:
- Replace services.memcached.socket by a boolean flag. This simplifies
our code, since we do not have to check if the user specifies a
path with a parent directory that should be owned by memcached
(/run/memcached/memcached.sock -> /run/memcached).
- Remove fixed uid/gid allocation. The only file ever owned by the
daemon is the socket that will be recreated on every start.
Therefore user and group ids do not need to be static.
- only create the memcached user, if the user has not specified a
different one. The major use case for changing option is to allow
existing services (such as php-fpm) opening the local unix socket.
If we would unconditionally create a user that option would be
useless.
apps.plugin requires capabilities for full process monitoring. with
1.9.0, netdata allows multiple directories to search for plugins and the
setuid directory can be specified here.
the module is backwards compatible with older configs. a test is
included that verifies data gathering for the elevated privileges. one
additional attribute is added to make configuration more generic than
including configuration in string form.
