There is an option for setup.exe to install a complete category.  To
make use of that you need to write a new setup.ini so that the packages
you've selected are members of that particular group.

They may say that they want this, but believe me that they actually
don't.  There's always some machines that will need a different
selection of packages, if not initially then somewhere down the road.

If you really want to clone an existing installation, then copy over
/etc/setup/installed.db into the new installation root and do a
reinstall (there's no command line option for that).  Alternatively, set
all the versions in installed.db to zero and then let setup.exe do an
"update", which is the default.
