I want /tmp in RAM

Hi,

I'm enjoying 1 Gb RAM, then I decided to allocate some RAM as temporary use.

I set in my /etc/fstab

/tmp                /dev/shm         tmpfs     size=256m                   0      0

But I'm not sure whether my /tmp is erased by boot procedures or because it's a real RAM.

Is there some test, to verify this?
Do I made wrong setting?

Re: I want /tmp in RAM

Don't you want something like this:

none    /tmp    tmpfs   nodev,nosuid,noexec,nodiratime,size=768M    0   0

That's what I'm running and my tmp is certainly in RAM and properly emptied. The size option gives an upperbound, I never reached it yet

I suppose you'd barely notice... I just like the idea and probably access time to cached documents etc is faster. But still, I don't think it really matters, I just like to experiment with stuff like this

Re: I want /tmp in RAM

It was a default setup in Arch a few years ago, btw.

Does anyone know why the default was changed?

Re: I want /tmp in RAM

IMHO, will reduce tear/wear on the HD, specially for unnecessary files, that are used as a simple placeholder.
Hard disks will do better on retaining important data, temporary files are accepted when RAM cannot suffice.

My dream would be to have a spindleless laptop. 64 Gb data storage, 16 Gb RAM and sata socket if HD or other removable disk will need.

if I need to copy a cd the temporary image goes to /tmp of course, but I don't have 700 mB in /tmp because I don't even have 700mB of ram.

O.K., that makes sense. Thanks for the explanation.
