Not only that! 
but also:
- dynamically configured optimal scheduler in boot time when the disk detected is mechanical or not (elive-udev package)
- discard optimized option in fstab (as said before)
- discard option also included for the encrypted layer (see /etc/crypttab)
- different filesystem selected for the auto-partitioning during installation if ssd is detected or not
- correct alignment of every partition created to their physical block to have an optimal work response (same for the encrypted layer and LVM structures)
- barrier option included for the root filesystem
- there's also more optimizations not specifically for ssd's
As you can see, there's a ton of optimizations that Elive loves to include by default, the sad thing is that nobody knows these details and even some people thinks that Elive is just "debian with enlightenment"
