Yes, I know. Take a look at part 3) THE LIVECD-ISO-TO-DISK METHOD:

You can use this method for DVD installer too, like this for example:

livecd-iso-to-disk --format
--reset-mbr /path-to-iso/SL-62-x86_64-2012-02-06-Install-DVD.iso /dev/sdc

I install machines like that who don't have any DVD readers.

Actually, this is the only method that works for me for the installer.
