Red Hat Linux 7.2: The Official Red Hat Linux Customization Guide
PrevChapter 1. Kickstart InstallationsNext

Starting a Kickstart Installation

To begin a kickstart installation, you must boot the system from a Red Hat Linux boot diskette or the CD-ROM and enter a special boot command at the boot prompt. If the kickstart file is located on a boot diskette that was created from the boot.img or bootnet.img image file, the correct boot command would be:

boot: linux ks=floppy

The linux ks=floppy command also works if the ks.cfg file is located on a vfat filesystem on a floppy diskette and you boot from the Red Hat Linux CD-ROM.

An alternate boot command for booting off the Red Hat Linux CD-ROM and having the kickstart file on a vfat filesystem on a floppy diskette is:

boot: linux ks=hd:fd0/ks.cfg

If you need to use a driver disk with kickstart, you can still have the kickstart file on a floppy disk:

boot: linux ks=floppy dd

The Red Hat Linux installation program looks for a kickstart file if the ks command line argument is passed to the kernel. The command line argument can take a number of forms:

ks=nfs:<server>:/<path>

The installation program will look for the kickstart file on the NFS server <server>, as file <path>. The installation program will use DHCP to configure the Ethernet card. For example, if your NFS server is server.example.com and the kickstart file is in the NFS share /mydir/ks.cfg, the correct boot command would be ks=nfs:server.example.com:/mydir/ks.cfg.

ks=http:<server>:/<path>

The installation program will look for the kickstart file on the HTTP server <server>:, as file <path>. The installation program will use DHCP to configure the Ethernet card. For example, if your HTTP server is server.example.com and the kickstart file is in the HTTP directory /mydir/ks.cfg, the correct boot command would be ks=http:server.example.com:/mydir/ks.cfg.

ks=floppy

The installation program looks for the file ks.cfg on a vfat filesystem on the floppy in drive /dev/fd0.

ks=hd:<device>/<file>

The installation program will mount the filesystem on <device> (which must be vfat or ext2), and look for the kickstart configuration file as <file> in that filesystem (for example, ks=hd:sda3/mydir/ks.cfg).

ks=file:/<file>

The installation program will try to read the file <file> from the filesystem; no mounts will be done. This is normally used if the kickstart file is already on the initrd image.

ks=cdrom:/<path>

The installation program will look for the kickstart file on CD-ROM, as file <path>.

ks

If ks is used alone, the installation program will configure the Ethernet card in the system using DHCP. The system will use the "bootServer" from the DHCP response as an NFS server to read the kickstart file from (by default, this is the same as the DHCP server). The name of the kickstart file is one of the following:

  • If DHCP is specified and the bootfile begins with a /, the bootfile provided by DHCP is looked for on the NFS server.

  • If DHCP is specified and the bootfile begins with something other then a /, the bootfile provided by DHCP is looked for in the /kickstart directory on the NFS server.

  • If DHCP did not specify a bootfile, then the installation program tries to read the file /kickstart/1.2.3.4-kickstart, where 1.2.3.4 is the numeric IP address of the machine being installed.

ksdevice=<device>

The installation program will use this network device to connect to the network. For example, to start a kickstart installation with the kickstart file on an nfs server that is connected to the system through the eth1 device, use the command ks=nfs:<server:>/<path> ksdevice=eth1 at the boot: prompt.

Quotes: Where a government has come into power through some form of popular vote, fraudulent or not, and maintains at least an appearance of constitutional legality, the guerrilla outbreak cannot be promoted, since the possibilities of peaceful struggle have not yet been exhausted.Whenever death may surprise us, let it be welcome if our battle cry has reached even one receptive ear and another hand reaches out to take up our arms.There are no boundaries in this struggle to the death. We cannot be indifferent to what happens anywhere in the world, for a victory by any country over imperialism is our victory; just as any country's defeat is a defeat for all of us.The amount of poverty and suffering required for the emergence of a Rockefeller, and the amount of depravity that the accumulation of a fortune of such magnitude entails, are left out of the picture, and it is not always possible to make the people in general see this.Many will call me an adventurer - and that I am, only one of a different sort: one of those who risks his skin to prove his platitudes.Whoever, in middle age, attempts to realize the wishes and hopes of his early youth, invariably deceives himself. Each ten years of a man's life has its own fortunes, its own hopes, its own desires.Life belongs to the living, and he who lives must be prepared for changes.Fools and sensible men are equally innocuous. It is in the half fools and the half wise that the danger lies.Destiny grants us our wishes, but in its own way, in order to give us something beyond our wishes.We must learn to be still in the midst of activity and to be vibrantly alive in repose.There is certainly no absolute standard of beauty. That precisely is what makes its pursuit so interesting.The conventional view serves to protect us from the painful job of thinking.Power is not something that can be assumed or discarded at will like underwear.People are the common denominator of progress. So - no improvement is possible with unimproved people, and advance is certain when people are liberated and educated.Faced with the choice between changing one's mind and proving that there is no need to do so, almost everyone gets busy on the proof.It is a far, far better thing to have a firm anchor in nonsense than to put out on the troubled sea of thought.The world is full of willing people, some willing to work, the others willing to let them.
