Nothing wrong with --pretend. I use it religiously for a couple of reasons. |
| 15 |
One is that when I want --quiet-build off, I can keep a complete list of the |
| 16 |
packages being merged in another screen tab, in case something fails. |
| 17 |
|
| 18 |
The other is that I don't want "emerge --ask" littering my emerge.log with |
| 19 |
stuff like this while I'm messing with USE flags, keywords, etc. and not |
| 20 |
actually committing to any emerges: |
| 21 |

Getting back to the actual topic :) I've noticed that more and more packages |
| 29 |
are getting pkg_pretend() checks so that ebuilds can abort before the build |
| 30 |
starts if something is missing, e.g. missing kernel modules or in the case of |
| 31 |
Xorg, gcc being too old. This might be what you're asking for, in a way. |
