Greetings all. Actually, I am following up on my thread from the other
day about putting speakup into a server distro of linux. I have an iso
image of the sme server distribution I want to use. thanks to Bill, I
have the identical kernel version rpms for redhat to match the
installation cd for this distro. I have never attempted to build an
iso image before. basically, on my test box, I want to modify the sme
isoimage by replacing the kernel rpms included with the ones I got from
octothorp and then make an iso image I can burn to cd and do an
installation on to another machine to see if ti works before i do this
to the machine which is running my mail ftp, etc.
wonder if this will work or break all kinds of things. I will also
have to modify their ks.cfg file to change the boot prompt default
label to pass speakup parameters.
Have never created a cd inlinux before having always cheated and used
easy cd creator 5
will just replacing the kernel rpms on a cd and then doing an
installation give me the new kernel or the original one on the cd which
the machine will boot from?
guess it will be an opportunity to learn some new stuff. any pointers
to creating iso images under linux would be cool I can always copy the
image to my windows box and burn it there but that is less of a
challenge.
will see what happens.
thanks. Brian.

Hi:
First, I highly recommend the CD writing howto. It's packed with lots of
useful info.
You will need mkisofs and something with which to write the image to a CD
(such as cdrecord). Here's what I'd do:
1. mount the iso image. This is a real neat thing you can do with linux,
saving you the bother of burning it to a CD first. Note that if you
already have it on a CD then you may as well not bother as you'll need to
transfer it all to your hard drive anyway. To mount the ISO image, do the
following:
mount -t iso9660 -o loop filename.iso /mountpoint
For example:
mount -t iso9660 -o loop image.iso /mnt
Note that you need the loopback device in your kernel in order to do this.
2. If you've mounted the iso, copy everything out into some other place on
your hard drive. If you've mounted a CD, do the same. The reason is that
neither the iso image or the CD itself will let you change the files
without moving them first.
3. change files as necessary.
4. Make the image with mkisofs. This is the tricky bit. You'll need to
make it bootable, and this is something I can't advise you on ... but the
howto will tell you what you need to know. Remember that you'll need to
change the kernel in the boot image on the CD.
5. Write the image to a CD. The bootable bit will be important here too.
Hope this helps to a point. Remember to get the latest version of any
howto you want to read. You can get the CD writing howto from
http://wt.xpilot.org/linux/
Geoff.

Hi,
Since you're using ks.cfg, I'll guess that your distro uses
Anaconda.
Install the anaconda and anaconda-runtime RPMs. mount the CD and use cp
-a to copy the contents to your HDD. Replace the RPM packages you find
there with the modified ones. You speak of CD in the singular. RH7 had
two. If you only have one, cd to /usr/lib/anaconda-runtime type:
"./genhdlist <path_to_installation_tree>". If you have two Cd's you'll
need to copy both of them to the HDD. The genhdlist command would
look like
this: "./genhdlist <path1> <path2> --withnumbers". If you really want to
go all the way, and you're sure that the version of Anaconda is the same
for SME and RH7.0, you could download the Anaconda packages from the same
place you got the kernel packages. They have the Speakup keymap built in.
The buildinstall command in the /usr/lib/\anaconda-runtime directory will
make a completely new installation tree. Since you use kickstart, this
might not be very important to you. Now for the CD. You can use the
strings command on the raw CD image to extract the commandline of the
mkisofs command that was used to create them. Pipe to grep mkisofs.
You'll want to edit out the version number such as 1.13. If you have any
questions, call or write.
HTH.
Bill
