Yes. But I have added a mfs for /tmp and would like to keep the maximum
of the remaining RAM for files---it will be mainly a file storing 
system and occasionally a file server, seldom processing data and seldom
with a connected user---so the quick availability of MAN related data
is not crucial.

And I want to avoid swapping to occur (with 1GB of RAM, should not
happen frequently the USB or eSATA->SATA connected disk + the ethernet
remote connection being the throttling) devices.

Thanks for the tip! (I haven't thought of the /dev/*...!!!)
