I am uncertain as to why the difference with the changes you had made,
and the size it returned, however I would suggest following the release
engineering process for creating a custom release.
http://www.freebsd.org/doc/en_US.ISO8859-1/articles/releng/index.html
In doing this process, I am sure you find it is a much cleaner process,
and more close in size to what you may expect.

Hi,
I am trying to create a custom ISO image of FreeBSD 6.4. The only
difference between the release ISO and this custom image is a modified
driver (amdsmb.ko). I did not create the new driver. I believe it was
backported from a later release.
I understand that this is not a backport of the driver but a hack but
the ISO size surprises me.
The steps I had followed (listed below) resulted in an ISO image of
around 1 GB while the original ISO image is around 600 MB. The new
image work boots fine but I am not sure why it is huge
Steps:
// mount the release ISO
# mdconfig -a -t vnode -f 6.4-RELEASE-i386-disc1.iso -u 0
# mount_cd9660 /dev/acd0 /mnt
# pwd
/usr/home/scott
# mkdir custom
# cd custom
// copy iso files to custom
# rsync -a /mnt .
# scp sc...@remote:/boot/kernel/amdsmb.ko boot/kernel/.
// wrap up in a ISO
# cd ..
#mkisofs -R -b boot/cdboot -no-emul-boot -o custom.iso custom
The ISO file is created successfully but is huge. I mounted it in
VirtualBox and boots just fine. I was able to install the OS (although
I have not checked the functionality of amdsmb changes yet)
I looked up information on creating custom ISO images but they had all
involved rebuilding the kernel while I am not sure if I need to do the
same Any leads is appreciated.
Thanks
Scott
