[IDEA] Put a list of available snapshots in /boot

[adepssimius]

@mk01 thank you very much for your detailed and very informative post. The bootmenu parameter looks like a fantastic piece of work and I will try it as soon as my rpi is unpacked (currently in the process of moving) along with the telnet parameter.

When using the telnet parameter, I assume that since I use reserved DHCP addresses I would need to also set the ip=dhcp parameter. From reading your explanation of the rescue parameter, I assume that if my system was in need of some manual intervention (me), I would have to add the rescue parameter in addition to the telnet and ip=dhcp parameters in order to actually assume control via telnet, correct?

Lastly, I am obviously not a linux guru by any means, but I would assume that at the recovery console since we are still running out of the initramfs that I would not be able to use wlan0 and I must use eth0 since the system loads kernel modules/drivers (please tell me which is the correct term) later on in the boot sequence. Is that also a correct assumption?

Lastly, thank you for all your hard work on xbian. IMO it is the most useful, feature-filled distro in the whole rpi community.
