Re: MacOS X equivalent of swapon/swapoff?

I hadn't thought about it that way; I guess I was still going by the 'old school' idea that there might be times when a process would be completely paged out (in other words, *swapping* rather than paging), and that therefore contiguous disk space would have been a good thing.

If you work out the statistics, I don't think there's any need for such a distinction (except in degenerate cases).

Another thing to think about is that having a separate swap _partition_ on a system with a single drive would likely decrease performance as the drive has to constantly seek between the system and swap partitions, which are going to be on different parts of the disk.

A separate swap drive would be another story, but in the real world that is only likely on servers and possibly high-end workstations.

That said, as a developer who has to keep multiple boot partitions (for different OS versions), I do wish Mac OS X provided an easy way to specify an alternate volume to use for all scratch allocations (VM, /tmp, etc.), rather than forcing them to be on the boot volume.

It's somewhat annoying to need 4GB free on the root volume in order to burn a DVD.

Allowing me to redirect all boot partitions' scratch storage to a single "big disk" would reduce the size of an individual boot partition significantly.

Ditto for user home directories (although I know how to do that with NetInfo).
