Subject: ramfs/tmpfs/shmfs doubt

Hello All,
I have a doubt regarding use Of ramfs .In which cases should i
use ramfs/shmfs/tmpfs/ramdisk and how page cache is used in these cases?
On my board i have 8 MB RAM and a Flash (to store Kernal and
Application code and persistent Application Data). Also i have no additional
device to use it as a swap.So if for swap i have to use a part of
RAM(Compressed Swap suggested on this mailing list earlier).
I am planning to create a file system at boot time in RAM and download
application binaries to that and run.RAM is limited so my requirement is
that i do not want to have two copies of data in the RAM (One in File
System i create and other one in Page Cache ).
What is the best available mechanism i should follow?
(Can i use ramfs/tmpfs to solve the above problem?)
Can i run a linux kernel disabling swapping (In my case no
additional device for swap is available) ?
Thanks a lot,
Anil
