+Frequently Asked Questions (FAQ)
+--------------------------------
+
+What's the difference between grml2hd and grml2usb?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+grml2hd installs a running grml system to a harddisk. When rebooting the
+harddisk installation can be modified and changes will find their way to the
+harddisk immediately. grml2usb copies just the compressed chroot filesystem
+(being the squashfs file), some further informational files and a bootloader to
+your device. This way you don't need as much space as with a harddisk
+installation (just a USB device with >=ISO size) and when rebooting the system
+your changes will be lost (even though a persistent root feature is
+work-in-progress). Think of using a better CD version: booting is (usually)
+faster, you don't need to burn a new CD when a new ISO version arrives (just
+install the new ISO using grml2usb) and you can carry additional files on a
+writable medium with yourself.
