What sort of filesystem image? ext2 or so, right? But then this is an
ext2 filesystem image, not a ramfs image.
say the file varfs, to
/dev/ram (yes, this isn't a ramfs) and mount it afterwords like this:
dd if=varfs of=/dev/ram
mount /dev/ram /var
What you're using here is a standard ramdisk. This has nothing to do
with a ramfs filesystem. You cannot build a "ramfs" filesystem image;
you can just populate the filesystem itself. You cannot copy this
"filesystem" to any storage device (except on a file by file base).
It just lives in the VFS cache.
Ah, I see. Thought I was wrong.
But then, what is the purpose of ramfs?
