Fedora core mkisofs question

[hkbq...@gmail.com]

Hello all,

I am trying to backup my FC2, which is running in a 4GB HDD to a DVD RW
regularly. In short I want to create a bootable DVD image. I have
search thru Googe and got some info + running some tests. The image I
can create, but the image is *NOT* bootable at all.

http://www.fedoraforum.org/forum/archive/index.php/t-1272.html

I think my problem is in the creation of the boot.img, but I don't know
how to create a boot image properly in FC2. Can somebody give me some
hint (or show me the command) in how to create a bootable DVD iso image
properly ?

*FC2 cannot create the boot image in a floppy*

Some error output..

[root@fagi root]# /sbin/mkbootdisk --verbose --iso --device boot.iso
`uname -r`
Installing isolinux... done
Copying /boot/vmlinuz-2.6.9-1.6_FC2... done.
Copying /boot/initrd-2.6.9-1.6_FC2.img... done.

Unknown file type (unallocated) /tmp/mkbootdisk.OB2867/.. - ignoring

Thanks
