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.
Instead of polluting the environment with environment variables which
are inherited by processes spawned from awesome, use the command line
argument "--search" to add things to the search path.
