[Grml] Installing grml on a USB Flash Drive

Hi, I know that you can install grml easily on a usb flash drive and was wondering if grml has any special options for flash drives installation, as, from my understanding, flash drives have a limited number of write and erase cycles before failure. Does grml allow you to write all hard disk changes to RAM (in a ramdisk) and then allow you to either commit these changes when closing your session? Does grml have any flash-friendly options? Thanks for your help.
