I just realized that cdboot does not contain the kernel as boot.flp used
to, so I guess /boot/kernel has to be there... So it does not seem to
work with mkisofs. I did
mkisofs -J -R -no-emul-boot -b ./cdboot -iso-level 3 -V FreeBSD_Custom
-o custom_FreeBSD_8_0_i386_cd.iso custom_FreeBSD_8_0_i386_cd
and it throws:
mkisofs: Uh oh, I cant find the boot image './cdboot'
I tried with the absolute path for cdboot and it does not help either.
From the mkisofs man page it says that -no-emul-boot has to be added if
the size of the image file is not 1200, 1440, or 2880 kB. I noticed that
the cdboot file is only 1.2 kB, so I guess -no-emul-boot is required...
Do you have an idea what could be wrong?
Thanks!

Great Thanks! So when I create a boot CD using the boot image, are the
kernel files contained in /boot/kernel read at all during boot?

Hi,
I would like to create a boot CD using FreeBSD 8.0 but I just noticed
that there is no existing boot.flp file for 8.0. What is the
alternative to get a boot image to create my CD image?
Thanks!
You just use the boot/cdboot file from the official CD/DVD, like this
(to write to a DVD)
growisofs -Z /dev/cd0 -speed 16 -J -R -no-emul-boot -b boot/cdboot
-iso-level 3 path-to-your-files
or use mkisofs with similar options to write an iso image, i.e.
mkisofs -J -R -no-emul-boot -b boot/cdboot -iso-level 3 -o
/path/to/your.iso path-to-your-files
