Running Debian Lenny from ramdisk
Greetings all-
I've got some questions about Lenny and running from ramdisk. Hoping someone can shed some light. ;-)
<textwall>
I have a very specific Debian Lenny based system I use for communications (think VoIP and RS232 serial). This installation is very 'pared down', only the essentials. I currently have an image that I write to new drives/systems using 'dd'. This works well, however, in some of the places I'm putting these systems, the power is horrible. After a few hundred power outages, the filesystems tend to need some TLC or are not recoverable (the underlying storage hardware, HDD or Flash device are fine).
So, my thoughts are to move to an installation where the entire OS is extracted from a tar.gz or img from the storage medium and run from RAM (ala ramdisk) and the actual storage is mounted R/O or simply not mounted at all. I understand this is possible but I've yet to find any recent (read Linux 2.6.x) documentation describing the process of installing a new system as such, or converting an existing installation to this method, let alone related to Debian.
Can anyone provide some pointers or instructions to get me started? I'm incredibly experienced with Linux, CentOS and Debian in particular, but I'm severely lacking in this department.

TLDR: How do I get Debian to run entirely from RAM?
Thank you!
Tim
