Hello,
I'm trying to add some files to /lib/firmware (for a Broadcom wireless card) on my Live CD.
Since it's read-only, this means having to go back and modifying the .iso file. I'm assuming the files I want are in centos-live.sqfs. How can I go about making these changes? I realize the firmware files can't be there to begin with, but so far, I've got no success in making these files available when the driver loads since AFAIK it's only going to look in /lib/firmware.
Thanks in advance.

No, these files are in usr.sqfs.
How can I go about making these changes?
# mkdir /mnt/loop1 /mnt/loop2 # mount -o loop CentOS-5.0-i386-LiveCD.iso /mnt/loop1 # mount -o loop -t squashfs /mnt/loop1/usr.sqfs /mnt/loop2 # cd /mnt/loop2/ ... # umount /mnt/loop2 # umount /mnt/loop1
-> Burn your modified iso file

Wow! Thank you!
I spoke with a couple people on #centos who didn't think it was possible to do. THANK you greatly.
I don't know what Knoppix does differently, but I noticed that their /lib/firmware was accessible on their live cd. May it be possible that in the future, the centos live cd's could do the same, or perhaps something like this could be made to work via a USB key?
In fact, I'll ask now; is it possible to mount my /lib/firmware off a USB key and do things THAT way, during startup, so that the broadcom driver finds the files there?
Thanks again!

I'm currently working on a new Live CD with increased functionnalities: http://lists.centos.org/pipermail/centos-devel/2007-July/003744.html
I recommend you to give it a try. The resulting Live CD is more flexible.
