update_seed has been very useful when dealing with perl/python version |
| 28 |
upgrades, where large swathes of packages need to be updated at the same |
| 29 |
time. I'm not sure if @changed-subslots has in any way resolved this, |
| 30 |
but it's convenient to have an override. |

Another example was a recent bash/readline update, where the stage3 had |
| 33 |
readline.so.5 and built the new stage1 bash against that, but installed |
| 34 |
readline.so.6 into the stage1root, hence the stage2 build was broken. |
