Unfortunately there is no correct answer here as we didn't consider |
| 19 |
this scenario when planning EAPI 7. We should have looked at Exherbo, |
| 20 |
which does make this important distinction. There is a bug report open. |

What I will say is that we should not attempt to executing anything |
| 25 |
from within ROOT or SYSROOT unless it known to be interpreted |
| 26 |
(e.g. a shell script) and there is no feasible alternative. I add that |
| 27 |
exclusion clause because I have been forced to do this with |
| 28 |
python-config. |
