How to configure Linux (am using Fedora 21) managed by systemd to boot to console (init 3) mode?
systemd has the concept of targets as a more flexible replacement for runlevels in sysvinit.
Runlevel 3 is emulated by multi-user.target. runlevel3.target is a symbolic link to multi-user.target.
You can switch to ‘runlevel 3’ by running
# systemctl isolate multi-user.target
On boot, systemd activates the target unit default.target whose job is to activate services and other units by pulling them in via dependencies. systemd parses its own kernel command line argument systemd.unit=.
This may be used to temporarily boot into the multi-user.target boot unit:
systemd.unit=multi-user.target
On some systems you have to disable the `lightdm.service` or `kde.service` or `gdm.service` whichever might be still active
# systemctl disable kde.service # systemctl disable lightdm.service # systemctl disable gdm.service
If your system still boots into gui despite the above steps:
On some systems you have to do one more thing: disable the lightdm.service or kde.service whichever might be still active
systemctl disable kde.service
or
systemctl disable lightdm.service
Thanks. gdm.service is another one to be disabled too.
