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
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.
