First, the --jobs option is good, but it is useless with only one package in the list. Second, apparently, when a user emerges exactly one package, the probability is high that he/she may have wanted to read the output of the build process -- as opposed to emerging many packages, where the user just wants to get it done. Based on this, the proposal is to implement a feature (which may be default or accessible via a command line option) that would make emerge behave just as if --jobs were not set if the count of packages to be emerged is exactly one. Please feel free to comment it, thanks. Reproducible: Always Steps to Reproduce:
Such an command line option already exists. It's called --jobs 1. And I'm against making this the default behavior if only one package is merged. I'm almost never interested in all the output and wouldn't have an option to hide it.
FWIW, -j1 also works. I don't like the idea of having an option for it to react automatically. Sorry. :)
