Nevertheless, only one runlevel can - be "active" at a given time, while systemd can activate multiple - targets concurrently, so the mapping to runlevels is confusing - and only approximate. Runlevels should not be used in new code, - and are mostly useful as a shorthand way to refer the matching - systemd targets in kernel boot parameters.</para> - - <table> - <title>Mapping between runlevels and systemd targets</title> - <tgroup cols='2' align='left' colsep='1' rowsep='1'> - <colspec colname="runlevel" /> - <colspec colname="target" /> - <thead> - <row> - <entry>Runlevel</entry> - <entry>Target</entry> - </row> - </thead> - <tbody> - <row> - <entry>0</entry> - <entry><filename>poweroff.target</filename></entry> - </row> - <row> - <entry>1</entry> - <entry><filename>rescue.target</filename></entry> - </row> - <row> - <entry>2, 3, 4</entry> - <entry><filename>multi-user.target</filename></entry> - </row> - <row> - <entry>5</entry> - <entry><filename>graphical.target</filename></entry> - </row> - <row> - <entry>6</entry> - <entry><filename>reboot.target</filename></entry> - </row> - </tbody> - </tgroup> - </table> - </refsect1> - - <refsect1> - <title>Description</title> - - <para><command>runlevel</command> prints the previous and current - SysV runlevel if they are known.</para> - - <para>The two runlevel characters are separated by a single space - character.
