Chapter 20. Additional Boot Options
do not specify this option at boot time, installation will fail, or the system will fail to boot
after installation completes.
noprobe
this command disables hardware detection and instead prompts the user for hardware information.
rescue
this command runs rescue mode. Refer to
information about rescue mode.
text
this command disables the graphical installation program and forces the installation program to
run in text mode.
vnc
this command allows you to install from a VNC server.
vncpassword=
this command sets the password used to connect to the VNC server.
noipv6
this command disables the default selection of ipv6 options during the installer stage 1 processing.
Ipv6 settings may still be made manually if this option is specified, but the default behavior will be
that Ipv6 settings are not enabled.
cmdline
The 3270 console (most often used during installation on IBM System z) does not recognize
terminal formatting entries common to most unix-style terminals. Specifying this option changes
the behavior of anaconda during kickstart installations so that console output on the 3270 is much
better. This option should not be used for regular, interactive installations.
RUNKS=1
This option is used to specify (usually in conjunction with the cmdline option) kickstart installation
for IBM System z.
