I am confused over the entire ramdisk concept for embedded systems. I think
several on this list wouldn't mind an explanation on why a large ramdisk
(>8192k, I assume) is "insane."
Example Scenario: I want to put a music player and a few large song files
on my assabet. These files take up 10 megs alone without any sort of
filesystem, etc. Now, being a novice, I see two options: (1) create a large
ramdisk of say, 16 megs {the option I thought was a good idea} or (2) create
several ramdisks, one with the kernel and basic OS, and another 1 or 2 for
the files {I have no idea how I would do this if it is even practical}.
To be clarified: (A) Why is a 16MB ramdisk "insane" {hope I am not taking it
out of context, Nicolas} and (B) how would I accomplish my scenario goal in
general?

Your filesystem is corrupted somehow. You should fix that before even
considering loging in.
Why do you want to put a 12MB filesystem into a ramdisk? This is completely
insane IMHO.
