Which version of FAI are you using? Current versions even include a
luks/cryptsetup example in the man page!?

I haven't used the cryptsetup part myself, but IMHO something like the following
should do the trick:

disk_config hda
primary  /boot  200  ext3  defaults
primary  -      0-   -     -

disk_config cryptsetup
luks     -      hda2  -  -

disk_config lvm
vg           my_vg  hda2
my_vg-root   /      10G  ext3  defaults

Obviously, you might want to add swap space (probably encrypted, and maybe also
tmp in there), more logical volumes, etc.

Hope this helps,
Michael
