adding a directory to a CD-image (.iso)

[Mikhail Teterin]

Hello!

I donwloaded an .iso-image (Solaris 10, actually), which is about 2.7Gb.

Before burning it to a DVD, I'd like to add a directory to the image. Is there 
a way to do it with tools available on FreeBSD -- mkisofs, growisofs, etc?

I don't want to recreate the main image from scratch, as I'm sure, I'll get 
the options wrong and it will not boot :-) Can I just add a directory to the 
existing iso8859 filesystem?

Thanks!
