Seems it does not work with network boot and default config.

I added:
logical -               120M:preserve_lazy     ext4  noauto 
createopts="-L MY-DATA"
to disk_config and (after zapping clean the disk) it got created [*]. 
But it seems it doesn't get mounted (at least a custom script did not 
find it mounted). I don't know FAI internals enough :(
Not a big issue, since it can be replaced by a few lines in a script:
#!/bin/bash
datadisk=/dev/disk/by-label/MY-DATA

if [ -e $datadisk ]; then
     mkdir -p /media/data
     mount $datadisk /media/data
     src=/media/data/$(hostname -s)
     if [ -d $src ]; then
         cp -r $src/ $target/
     fi
fi


[*] Currently wrestling with "preserved partition /dev/sda7 does not end 
at a cylinder boundary, parted may fail to restore the partition" 
messages in error.log... "disk_config" line have "align-at:1M", isn't it 
enough?
