I've noticed something surprising (to me) about the order that 'emerge -auvND world' decides to install/upgrade/reinstall packages. The situation is as follows:
* A large number of packages need to be build/installed/reinstalled * Hit control-C during the build of package X * Restart 'emerge -auvND world' I expect that it will start by building package X and resume with the remainder of the packages in the same order as before. Often it does not. The order of package bilds often seems to be quite different after the interruption than it was the first time -- often X is a fair ways down the list. Why is that? -- Grant
