I am in full agreement there... It's easy to see that applications do
not swap out overnight; but i'm having difficulty trying to find a way
to demonstrate the other part. I guess timing the "linking the kernel
with full debug" on a low memory box is measurable.
I should have said - finding a swappiness that ensures not swapping out
applications with updatedb, then using that same swappiness value to do
the linking test.
Please excuse me, but is that viable at all? IMHO, it's just like trying
to tune a radio including volume with only one knob. I don't say it
won't work, but the probability that it will is rather small, it seems

Well that's what we want. I cant remember other desktop operating
systems setting a root only control between night and day, or between
copying ISOs and running applications or...
I agree, but isn't it related to the fact that other desktop OSes usually don't run anything like updatedb nightly?
Perhaps we need a bit more sophisticated swap algorithm than other OSes do. For example, couldn't we add an additional parameter to control the swapping "behavior", apart from the swappiness? Something like adding the second knob in my radio example? Just thinking,
