Hi!

Does anone of you know if it is save to run emerge on several terminals at the same time for merging several packages at once?

...thanks,
chris

With the fact that compiles run in a "sandbox" and given Portage's config file protection, you ought to be good. Nothing critical should be overwritten, and as long as they don't install at exactly the same instant, I don't see how bad things could happen.

Hi!

You'll be ok as long as you do the parallel merge for dependency indepent apps. If you try to merge packages that have common dependencies or depend on each other you may or may not run into problems.

An obviously simple example of a parallel merge doomed to failure: mozilla and galeon, there is no way that mozilla would finish merging in time to satisfy the dependencies of galeon.

While that is a simple example, there are much subtler instances that won't work either.

It's probably better to just merge them one after the other with one command, since they'd only be stealing cpu cycles from each other while compiling anyway.

eg:
emerge mozilla galeon xmms whathaveyou

You could emerge --fetchonly packages in one window while ones you've downloaded compile in the other.
