As a user, can I get a large +1 to that. For me, it is usually Seamonkey, Firefox, Libreoffice, that big qt package or some combination of two or more of them. I've had times where all of those just happen to upgrade at the same time. My solution was to put those on spinning rust while using tmpfs for everything else and if needed, using --exclude to put off one or more of them then do those later. While I like the general idea of this, and would love to see emerge be able to handle it without failures, I'm not sure how emerge or it's options can prevent it without slowing down other packages. My thinking, have emerge trigger when certain packages are in the upgrade list and only allow one package in that list to update at a time. For example. If Firefox, Libreoffice and that qt package are in the list of upgrades, whichever hits first causes the others to wait until the first one is done. That will make it so only one large package is being upgraded at a time and be able to have fast settings for other smaller and less memory hungry packages as well. How to do that, I'm not a coder so no idea but I know there are some awesome coders here who may can find a way. If that idea is even something that could be done. Since I rarely post here, keep up the great work. :-D Dale :-) :-)
