ISO Image Size Increasing

[jhall at vandaliamo.net]

I have run into a rather weird problem, that I am not sure how to correct.

I have created a bootable CD for my FreeBSD systems which is approximately
234 MB in size.  While deploying the image, I found an error I would like
to correct.  All I am doing is adding a symlink to a folder in the /home
directory.

Please let me know if you see anything flawed in my procedure which may be
causing this problem.

1.  Create a directory to work in /home/CDImage.

2.   Copy the existing image to the /home/CDImage directory.
    tar -cpf - /cdrom | tar -xpf -

3.  Add the necessary symlink.

4.  Create the ISO image.
    /usr/local/bin/mkisofs -allow-leading-dots -l -R -T -iso-level 4 -b
boot/cdboot -no-emul-boot -o fwcd.iso CDImage


The image copied from the CD is approximately 234 MB in size, and the
image created by mkisofs is 664 MB.

Any suggestions would be greatly appreciated.

Thanks,


Jay
