Missing Sections in FAI Documentation

[Itamar Gal]

Dear FAI Users:

While reading through the official FAI documentation I noticed that
two sections appear to be empty, specifically the section named
"Extract base file":

http://fai-project.org/fai-guide/#_a_id_extrbase_a_extract_base_file

and the (adjacent) section named "Debconf preseeding":

http://fai-project.org/fai-guide/#_a_id_debconf_a_debconf_preseeding

Is there content missing from the documentation? Or are these sections
no longer relevant?

Any feedback would be appreciated. Thanks!

Cheers,
Itamar
