Re: Do we need SWAP Space?

In terms of virtualizing like xen, i think it will be necessary to have a swap. For example you start two or more OSs and parts of the inactive one is sent to the swap to give the active OS more Resources.

xen does not have burstable memory access across xen instances. Ram is divided amoung dom0/domU's and each instance has it's own swap.

I am not sure about other virtualization software.

Re: Do we need SWAP Space?

Verdict:

If you have enough physical memory installed and know what applications run on your machine and how much memory they need, you do not need a Swap Partition.

But at least one question:

Is it necessary or useful to edit the configs of the System: rc.sysinit rc.shutdown,
if you dont have a swap. So the System dont have to activate or deactivate something which is not there.

You don't have to change anything. Scripts only care if you have defined "/" somewhere in /etc/fstab or  /etc/crypttab
