[systemd-devel] Trying to resolve user level systemd unit journal not writing to local user journal

[SCOTT FIELDS]

Because of the documentation for the 'logsdirectory' option for unit files.

https://www.freedesktop.org/software/systemd/man/latest/systemd.exec.html

--

RuntimeDirectory=, StateDirectory=, CacheDirectory=, LogsDirectory=, ConfigurationDirectory=
These options take a whitespace-separated list of directory names. The specified directory names must be relative, and may not include "..". If set, when the unit is started, one or more directories by the specified names will be created (including their parents) below the locations defined in the following table. Also, the corresponding environment variable will be defined with the full paths of the directories. If multiple directories are set, then in the environment variable the paths are concatenated with colon (":").
Table 2. Automatic directory creation and environment variables
Directory       Below path for system units     Below path for user units       Environment variable set
RuntimeDirectory=       /run/   $XDG_RUNTIME_DIR        $RUNTIME_DIRECTORY
StateDirectory= /var/lib/       $XDG_STATE_HOME $STATE_DIRECTORY
CacheDirectory= /var/cache/     $XDG_CACHE_HOME $CACHE_DIRECTORY
LogsDirectory=  /var/log/       $XDG_STATE_HOME/log/    $LOGS_DIRECTORY
ConfigurationDirectory= /etc/   $XDG_CONFIG_HOME        $CONFIGURATION_DIRECTORY

Granted...this states the directory will be created in the case of user units...and does not state that it would actually put the log there. But it doesn't make a lot of sense to state the given behavior and not use it

Why do you expecting that?
