That's ugly and bad. You should use a hook for that.

Write a shell hook, not a perl script that just calls shell commands.

Hook are perfectly for this!

Create a file hooks/partition.MYHARDWARE:

#! /bin/sh

mkfs.ext2 /dev/hda3
mkfs.ext2 /dev/hda6
<echo or cat commands for creating fstab and disk_var.sh>
skiptask partition


Now, if the class MYHARDWARE is defined your is will be executed
(chmod a+rx) before the task partition is called. The command skiptask
tells FAI to skip the normal task partition so setup_harddisks is not
called. You also have to create the file disk_var.sh and the fstab
file in this hook.
