+ <listitem><para>Controls whether

+ <varname>$XDG_RUNTIME_DIR</varname>
+ runtime directory for each user who
+ logs in. Takes a size in bytes,
+ optionally suffixed with the usual K, G,

+ (IEC). Alternatively, a numerical
+ percentage suffixed by <literal>%</literal>
+ may be specified, which sets the size
+ limit relative to the amount of

+ as much memory as is needed.
