'cobbler buildiso <parameters>' sounds good for these requirements - apart of
the last one, cant comment on that.

I didnt see buildiso as configurable directly, but you can use a workflow like
this, wrapped in a small shellscript that not to hard for daily use:
# generate iso with default to local
cobbler buildiso --profiles='' --systems=sakura
# modify defaulting to your host
sed -ie 's,^DEFAULT.*,DEFAULT sakura,' /buildiso/isolinux/isolinux.cfg
# generate custom iso using the mkiso-commang also buildiso was using
mkisofs -o /root/generated.iso -r -b isolinux/isolinux.bin -c isolinux/boot.cat
\
-no-emul-boot -boot-load-size 4 -boot-info-table -V Cobbler\ Install -R
\
-J -T /buildiso

Tried older Fedoras/Centos/RHEL for fun?
The requirements increased over time.
