If you don't pipe all output from emerge to a file, you will miss a lot of information when you do large updates. If all einfo are stored in a buffer until emerge finished and then display it, you get all the information visible and you will easily find all important infromation. Reproducible: Always Steps to Reproduce: 1. emerge -u world Actual Results: You will miss all the information echoed from the ebuild, as you won't have an unlimited text/scroll buffer. Expected Results: The information is shown after all ebuilds has been finished or saved to a default log file, eg /tmp/emerge-200703041206.einfo
