[Fedora-livecd-list] How To Create A Custom Fedora-7-Live-i386CD?

[Ciba LO]

Hello Jeremy, 
 
Thank you very much for replying to my post.
 
I tried your suggestion using livecd-tools with base-on option
to add the rt73usb-firmware package.  First, I put the firmware
and the image under /home/repodata.

# cd /home/repodata/
# ls -la
total 716972
drwxr-xr-x  2 root root      4096 2007-11-21 15:01 .
drwxr-xr-x 23 root root      4096 2007-11-21 19:52 ..
-rwxr-xr-x  1 root root 733427712 2007-11-11 15:56 Fedora-7-Live-i686.iso
-rwxr-xr-x  1 root root       156 2007-11-11 16:07 Fedora-7-Live-i686.iso.md5
-rwxr-xr-x  1 root root       301 2007-11-11 16:05 Fedora-7-Live-i686.iso.sha
-rwxr-xr-x  1 root root      5655 2007-09-27 01:40 rt73usb-firmware-1.8-4.noarch.rpm
# 

After, adding rt73usb-firmware to and removing gnome-games from the existing iso image.  
I got the error messages displayed as follows.

What am I missing?  Thank you in advance.

By the way, how to remove the Fedora trademarks from the image.

If you look at the README in the livecd-tools package, you'll see a
description of the baseon option (-b) to add things to an existing live
image.  Or alternately, you can just modify the configs used for the
Fedora 7 image and rebuild the entire image

But note that if you are wanting to include things which are not
included in Fedora (such as the bcm firmware) and then distribute the
result, you'll also need to remove the Fedora trademarks from the image
