FWIW: In an idealistic, but naive attempt, I've submitted a patch to |
| 2 |
upstream sed that adds an --error-if-unmodifed option [1]. Fellow Gentoo |
| 3 |
developers where quick to point out in #gentoo-dev that this patch |
| 4 |
barley scratches the surface of the sphere where sed could mutate state. |
| 5 |
It appears that --error-if-unmodifed in sed can only be reliable |
| 6 |
implemented if --inplace is used, by basically mimicking what Ionen's |
| 7 |
esed class does/did. |

This made me wonder if fixing this in sed is really the ideal solution. |
| 10 |
However, Ionen also closed the PR due to "having seconds thoughts" [2]. |

I guess this leaves us with qa-sed from app-portage/iwdevtools. Which is |
| 13 |
probably not the worst outcome. |
