What would you suggest? Will it be possible to append a bootoption to the kernel of fai install to change the class from DUALBOOT to SINGLEBOOT ? or is there a better way to do that?

We are using FAI to install dualboot machines, even though we're not 
using OPSI but Unattended to install windows on them. But for the FAI 
part, this doesn't matter.
We do just like you suggested, append a class named "DUALBOOT" to these 
machines, which will then use a different disk layout and preserve the 
first primary partition. We are using fixed class assignments to 
hostnames (vi $FAI_CONFIG_SRC/class/50-host-classes) instead of kernel 
boot options. If you want to detect an existing windows installation and 
create classes automatically, you can take a look at os-prober. 
os-prober (at least in Debian/Ubuntu) also automatically takes care of 
creating the necessary GRUB entry on the machines to boot windows, if 
present.
We do not shrink partitions, however, so I cannot help you with that. 
Since we're not storing any user data on local disks, todays disk sizes 
are way bigger than we need, so we just install each OS on a 40-80GB 
partition and leave the rest empty for future use.
