I am in the process of creating a bootable cd which uses kickstart to
automatically install a set of software then reboots the machines. I
have encountered many problems, and want all packages to be included on
the CD. I have not seen any manuals, or how-to guides anywhere. If has
any they can point me to, it would be very appreciated. One last
question I have, what happened to the 'genhdlist' in anaconda-runtime
package for Fedora Core 6? (I know this is a redhat list, and sorry if
that question was off topic)
I did something very like this, but for a network install. Here's what I
think will work.
1. Loop-mount the ISO (or mount the boot disk),
2. Find the relevant initial ramdisk in the isolinux directory.
3. Copy it to somewhere you can read/write.
4. Uncompress it using gunzip:
mv initrd initrd.gz
gunzip initrd
You now have a file with the original name, you can play with it, and
you don't _have_ to compress it.
5. Unpack the initial ramdisk; it's a cpio archive, easily done.
6. Put your ks file into the inird root directory
7. Create a new file initrd using cpio
8. Optionally, copy the isolinux are to where you can edit it. Change
the boot params. Note, it might be simplest to unpack the entire ISO:-)
9. Use a magic incantation as you use mkisofs to make a new ISO image.
Note, I mostly do network installs. My procedure is necessarily a little
different from what you want, as I use a PXE layout that generally has
my kernel etc outside my install tree, so I don't have to worry about
putting it all back togetner.
Here are some useful fragments gleamed from my .bash_history:
cd /tftpboot/PXE/linux-install/RHEL/4.90/initrd
cpio --extract --make-directories --preserve-modification-time \
--numeric-uid-gid <../initrd.img.orig
find . | sort | cpio --help >../initrd.img
label jerry
kernel /linux-install/RHEL/4.90/vmlinuz
append initrd=/linux-install/RHEL/4.90/initrd.img \
ramdisk_size=8192 ksdevice=link vga=6 ks=file:///jerry.ks upgradeany
Note the ks= - this specifies the ks file inside the initrd image.
pushd initrd;find . | sort | cpio --create -c | gzip -9 \
> ../initrd.img ;popd;ls -l
Oh, I did compress it!
