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. + + + Mapping between runlevels and systemd targets + + + + + + Runlevel + Target + + + + + 0 + poweroff.target + + + 1 + rescue.target + + + 2, 3, 4 + multi-user.target + + + 5 + graphical.target + + + 6 + reboot.target + + + +
+ + + + Description + + runlevel prints the previous and current + SysV runlevel if they are known. + + The two runlevel characters are separated by a single space + character. If a runlevel cannot be determined, N is printed + instead.
