27.4. Sample Kickstart Configurations 27.4.1. Advanced Partitioning Example The following is an integrated example showing the clearpart , zerombr , part , raid , volgroup , and logvol Kickstart options in action: Example 27.10. Advanced Partitioning Example This advanced example implements LVM over RAID, as well as the ability to resize various directories for future growth. First, the clearpart command is used on drives hda and hdc to wipe them. The zerombr command initializes unused partition tables. Then, the two drives are partitioned to prepare them for RAID configuration. Each drive is divided into five partitions, and each drive is partitioned into an identical layout. The part uses these pairs of physical partitions to create a software RAID device with RAID1 level (mirroring). The first four RAID devices are used for / (root), /safe , swap and /usr . The fifth, largest pair of partitions is named pv.01 and will be used in the following part as a physical volume for LVM. Finally, the last set of commands first creates a volume group named sysvg on the pv.01 physical volume. Then, three logical volumes ( /var , /var/freespace and /usr/local ) are created and added to the sysvg volume group. The /var and /var/freespace volumes have a set size of 8 GB, and the /usr/local volume uses the --grow option to fill all remaining available space. 27.4.2. User Input Example The following is an example showing how to prompt the user for input, and then read that input and save it as a variable, using bash: Example 27.11. User Input Example Due to the way Kickstart operates, the script must switch to a new virtual terminal before reading input from the user. This is accomplished by the exec < /dev/tty6 > /dev/tty6 2> /dev/tty6 and chvt 6 commands. The read USERINPUT reads input from the user until enter is pressed, and stores it in the variable USERINPUT . The echo -n "You entered:" "USDUSERINPUT" command displays the text You entered: followed by the user's input. Finally, the chvt 1 and exec < /dev/tty1 > /dev/tty1 2> /dev/tty1 commands switch back to the original terminal and allow Kickstart to continue installation. 27.4.3. Example Kickstart file for installing and starting the RNG daemon The following is an example Kickstart file which demonstrates how to install and enable a service, in this case the Random Number Generator (RNG) daemon, which supplies entropy to the system kernel: Example 27.12. Example Kickstart file for installing and starting the RNG daemon The services --enabled=rngd command instructs the installed system to start the RNG daemon each time the system starts. The rng-tools package, which contains the RNG daemon, is then designated for installation.
