When finished, you may include the file preservation list in the kickstart profile to be used
on systems containing those files. Refer to Section 6.4.10.3
Creating Kickstarts
for precise
steps.
6.4.10.11. Building Bootable Kickstart ISOs
While you can schedule a registered system to be kickstarted to a new operating system
and package profile, it is also useful to be able to kickstart a system that is not registered
with RHN, or does not yet have an operating system installed. One common method of
doing this is to create a bootable CD-ROM that is inserted into the target system. When the
system is rebooted, it boots from the CD-ROM, loads the kickstart configuration from the
RHN Servers or your Satellite, and proceeds to install Red Hat Enterprise Linux according
to the kickstart profile you have created.
To do this, copy the contents of
/isolinux
from the first CD-ROM of the target distri-
bution. Then edit the
isolinux.cfg
file to default to ’ks’. Change the ’ks’ section to the
following template:
label ks
kernel vmlinuz
append text ks={url} initrd=initrd.img lang= devfs=nomount \
ramdisk_size=16438 {ksdevice}
The URL can be obtained from the
Kickstart Details
page. It will look something like
this:
http://my.sat.server/kickstart/ks/org/
<
alphanumeric string
>
/label/my-rhel3-as-ks
IP addressed-based kickstart URLs will look something like this:
http://my.sat.server/kickstart/ks/mode/ip_range
The kickstart distribution selected by the IP range should match the distribution from which
you are building, or errors will occur. {ksdevice} is optional, but looks like:
ksdevice=eth0
It is possible to change the distribution for a kickstart profile within a family, such as RHEL
AS4 to RHEL ES4, by specifying the new distribution label. Note that you cannot move
between versions (2.1 to 3) or between updates (U1 to U2).
Next, you may customize
isolinux.cfg
further for your needs, such as by adding mul-
tiple kickstart options, different boot messages, shorter timeout periods, etc.
Next, create the ISO as described in the
Making an Installation Boot CD-ROM
section of
the
Red Hat Enterprise Linux 3 Installation Guide
. Alternatively, issue the command:
