+ prefixed with
+ <literal>System</literal> apply to the
+ journal files when stored on a
+ persistant file system, more

+ <filename>/var/log/journal</filename>. The
+ options prefixed with
+ <literal>Runtime</literal> apply to
+ the journal files when stored on a
+ volatile in-memory file system, more
+ specifically
+ <filename>/run/log/journal</filename>. The
+ former is used only when
+ <filename>/var</filename> is mounted,
+ writable and the directory
+ <filename>/var/log/journal</filename>
+ exists. Otherwise only the latter
+ applies. Note that this means that
+ during early boot and if the
+ administrator disabled persistant
+ logging only the latter options apply,
+ while the former apply if persistant
+ logging is enabled and the system is
+ fully booted
+ up. <varname>SystemMaxUse=</varname>
+ and <varname>RuntimeMaxUse=</varname>
+ control how much disk space the
+ journal may use up at
+ maximum. Defaults to 10% of the size
+ of the respective file
+ system. <varname>SystemKeepFree=</varname>
+ and
+ <varname>RuntimeKeepFree=</varname>
+ control how much disk space the
+ journal shall always leave free for
+ other uses if less than the disk space
+ configured in
+ <varname>SystemMaxUse=</varname> and
+ <varname>RuntimeMaxUse=</varname> is
+ available. Defaults to 5% of the size
+ of the respective file
+ system. <varname>SystemMaxFileSize=</varname>
+ and
+ <varname>RuntimeMaxFileSize=</varname>
+ control how large individual journal
+ files may grow at maximum. This
+ influences the granularity in which
+ disk space is made available through
+ rotation, i.e. deletion of historic
+ data. Defaults to one eigth of the
+ values configured with
+ <varname>SystemMaxUse=</varname> and
+ <varname>RuntimeMaxUse=</varname>, so
+ that usually seven rotated journal
+ files are kept as
+ history. <varname>SystemMinFileSize=</varname>
+ and
+ <varname>RuntimeMinFileSize=</varname>
+ control how large individual journal
+ files grow at minimum. Defaults to
+ 64K. Specify values in bytes or use
+ K, M, G, T, P, E as units for the
+ specified sizes. Note that size limits
+ are enforced synchronously to journal
+ files as they are extended, and need
+ no explicit rotation step triggered by
+ time.</para></listitem>
