The light installer is 15MB.

Yes, in theory but it is a lot of work to distribute and maintain 3
installers.  Even convincing my co-hackers to keep the light installer
was not easy.

You may build your own installer of course.  The installer is a meta
package and using a decent Debian OS a new installer is easy to build.

The installer can't do that out of the box.

If the gpg-agent fails it gfails and it won't corrupt any data.

It is not a moster; rthe installer is only that larger becuase it
includes the GTK+ libraries a full mail client and GPA.

The faked-system-time option is a debug option we need to run the
regression tests.  If you merely want to create your keys with an other
creation date you may use a parameter file:

  @item  Ceation-Date: @var{iso-date}
  Set the creation date of the key as stored in the key information and
  which is also part of the fingerprint calculation.  Either a date like
  "1986-04-26" or a full timestamp like "19860426T042640" may be used.
  The time is considered to be UTC.  If it is not given the current time
  is used.

The batch key generation and that parameter is supported by all
