 I guess certain users want to know how to create bootable CD
 and it isn't relevant to installation.
 We also have to clarify the definition of "bootable"
 (make BIOS/firmware load a binary, load a kernel from CD, or
  get single user prompt with working file system?),
 but probably it's enough to mention the following command
 that uses the ElTorito specification without old floppy emulation:
 % makefs -t cd9660 -o 
output.iso /PATH/TO/cdsoureces_dir
 It might be worth to mention the following topics:
 - how to fetch sources and build tools to get makefs(8)
   (mention guide pages?)
 - how to prepare root file system
   (extract base/etc/kern sets, or
    put miniroot.kmod with "load" command in boot.cfg(5)?)
 - how to set permissions properly in output iso (by makefs(8) -F spec)
 but I'm not sure if it's in the scope of the document.
