\fBmkksiso\fP is a tool for creating kickstart boot isos. In it\(aqs simplest form
|
|
you can add a kickstart to a boot.iso and the kickstart will be executed when
|
|
the iso is booted. If the original iso was created with EFI and Mac support the
|
|
kickstart boot.iso will include this support as well.
|
|
.sp
|
|
\fBmkksiso\fP needs to be run as root, it depends on mounting the original iso
|
|
and you need to be root to be able to do that. The host system architecture
|
|
needs to match that of the iso. \fBmkksiso\fP will raise an error if it finds a
|
|
\&.discinfo on the iso with a mismatched arch.

.SH CREATE A KICKSTART BOOT.ISO OR DVD
|
|
.sp
|
|
Create a kickstart like you normally would, kickstart documentation can be
|
|
\fI\%found here\fP, including the
|
|
\fBurl\fP and \fBrepo\fP commands. If you are creating a DVD and only need the
|
|
content on the DVD you can use the \fBcdrom\fP command to install without a
|
|
network connection. Then run \fBmkksiso\fP like this:
|
|
.INDENT 0.0
|
|
.INDENT 3.5
|
|
.sp
|
|
.nf
|
|
.ft C
|
|
mkksiso /PATH/TO/KICKSTART /PATH/TO/ISO /PATH/TO/NEW\-ISO
|
|
.ft P
|
|
.fi
|
|
.UNINDENT
|
|

|
.sp
|
|
This will create a new iso with the kickstart in the root directory, and the
|
|
kernel cmdline will have \fBinst.ks=...\fP added to it so that it will be
|
|
executed when the iso is booted (be careful not to boot on a system you don\(aqt
|
|
want to wipe out! There will be no prompting).
|
|
.sp
|
|
By default the volume id of the iso is preserved. You can set a custom volid
|
|
by passing \fB\-V\fP and the string to set. The kernel cmdline will be changes, and the iso will have th custom volume id.
|
|
eg.:
|
|
.INDENT 0.0
|
|
.INDENT 3.5
|
|

|
|

.SH ADDING PACKAGE REPOS TO A BOOT.ISO
|
|
.sp
|
|
You can add repo directories to the iso using \fB\-\-add /PATH/TO/REPO/\fP, make
|
|
sure it contains the \fBrepodata\fP directory by running \fBcreaterepo_c\fP on it
|
|
first. In the kickstart you can refer to the directories (and files) on the iso
|
|
using \fBfile:///run/install/repo/DIRECTORY/\fP\&. You can then use these repos in
|
|
the kickstart like this:
|
|
.INDENT 0.0
|
|
.INDENT 3.5
|
|
.sp
|
|
.nf
|
|
.ft C
|

.SH CREATE A LIVEIMG BOOT.ISO
|
|
.sp
|
|
You can use the kickstart \fI\%liveimg command\fP,
|
|
to install a pre\-generated disk image or tar to the system the iso is booting
|
|
on.
|
|
.sp
|
|
Create a disk image or tar with \fBosbuild\-composer\fP or \fBlivemedia\-creator\fP,
|
|
make sure the image includes tools expected by \fBanaconda\fP, as well as the
|
|
kernel and bootloader support. In \fBosbuild\-composer\fP use the \fBtar\fP image
|
|
type and make sure to include the \fBkernel\fP, \fBgrub2\fP, and \fBgrub2\-tools\fP
|
|
packages. If you plan to install it to a UEFI machine make sure to include
|
|
\fBgrub2\-efi\fP and \fBefibootmgr\fP in the blueprint.
|
|
.sp
|
|
Add the \fBroot.tar.xz\fP file to the iso using \fB\-\-add /PATH/TO/ROOT.TAR.XZ\fP,
|
|
and in the kickstart reference it with the \fBliveimg\fP command like this:
|
|
.INDENT 0.0
|
|
.INDENT 3.5
|
|
.sp
|
|
.nf
|
|
.ft C
|
|
liveimg \-\-url=file:///run/install/repo/root.tar.xz
|
|
.ft P
|
|
.fi
|
|
.UNINDENT
|
|
.UNINDENT
|
|
.sp
|
|
It is also a good idea to use the \fB\-\-checksum\fP argument to \fBliveimg\fP to be
|
|
sure the file hasn\(aqt been corrupted:
|
|
.INDENT 0.0
|
|
.INDENT 3.5
|
|
.sp
|
|
.nf
|
|
.ft C
|
|
mkksiso \-\-add /PATH/TO/root.tar.xz /PATH/TO/KICKSTART /PATH/TO/ISO /PATH/TO/NEW\-ISO
|
|
.ft P
|
|
.fi
|
|
.UNINDENT
|
|
.UNINDENT
|
|
.sp
|
|
When this iso is booted it will execute the kickstart and install the liveimg
|
|
contents to the system without any prompting.
|
|
.SH HOW IT WORKS
|
|
.sp
|
|
\fBmkksiso\fP first examines the system to make sure the tools it needs are installed,
|
|
it will work with \fBxorrisofs\fP or \fBmkisofs\fP installed. It mounts the source iso,
|
|
and copies the directories that need to be modified to a temporary directory.
|
|
.sp
|
|
It then modifies the boot configuration files to include the \fBinst.ks\fP command,
|
|
and checks to see if the original iso supports EFI. If it does it regenerates the
|
|
EFI boot images with the new configuration, and then runs the available iso creation
|
|
tool to add the new files and directories to the new iso. If the architecture is
|
|
\fBx86_64\fP it will also make sure the iso can be booted as an iso or from a USB
|
|
stick (hybridiso).
|
|
.sp
|
|
The last step is to update the iso checksums so that booting with test enabled
|
|
will pass.
