memory file system on linux

[Ramesh Panuganty <rameshpanuganty@yahoo.com>]

Hi,

I am new to this group and came here while looking for
a specific information. Can someone help me in getting
the information (please reply to me directly).

Are there any memory file systems on linux with which
I can maitain the entire file system on RAM?
    - will /dev/ram come to of any help for me?
    - I had read about something like 'tmpfs' on SunOS
which is a virtual filesystem that is entirely
resident in the memory (probably shares the space with
swap)

Actually, I will tell you what I am looking for...

I have a 32MB IDE-disc and a 64MB RAM on my machine.
But these small IDE-discs support very limited number
of I/O Operations in their life time. Hence to limit
the I/O, I want to keep the 32MB file system itself on
RAM and do a read-write only once during bootup and
shutdown.

Is there anyway, I can achieve this?
