Twelve different types of *units*, of which service and target are two. A target is like a runlevel (it groups units together), except that more than one can be active at a time. A target can be marked "AllowIsolate=yes", which means that it can be treated like a sysvinit runlevel (start everything listed in it and stop everything else). Note also that backward-compatible symlinks are provided in /usr/lib/systemd/system for the targets that correspond to the "classical" sysvinit runlevels: runlevel0.target -> poweroff.target runlevel1.target -> rescue.target runlevel2.target -> multi-user.target runlevel3.target -> multi-user.target runlevel4.target -> multi-user.target runlevel5.target -> graphical.target runlevel6.target -> reboot.target https://fedoraproject.org/wiki/Systemd#How_do_I_change_the_target_.28runlevel.29_.3F https://fedoraproject.org/wiki/SysVinit_to_Systemd_Cheatsheet -- Glenn Holmer (Linux registered user #16682) "After the vintage season came the aftermath -- and Cenbe." -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
