For the moment, could we have a workaround? |
| 9 |
1. portage should keep lockfiles while it makes a call to wget/$FETCH so |
| 10 |
that duplicate instances don't blow up (you can cause this even on a |
| 11 |
single machine, no need for NFS). |
| 12 |
2. as something extra from the above, say you are merging a bunch of |
| 13 |
packages, and one of them is being downloaded by an alternate process. |
| 14 |
Instead of failing immediately, portage should find the NEXT thing that |
| 15 |
doesn't have an dependancies in the depgraph (another pure leaf node so |
| 16 |
to speak), and run that way. If there is nothing else that can be done |
| 17 |
without waiting for the other existing process, then we can throw a |
| 18 |
temporary error. |

Long term this would be ideal, esp. if merged with functionality like |
| 28 |
redhat's RHN subscriptions (able to push updates to a group of machines |
| 29 |
automatically, and get error messages if it fails). This is one of those |
| 30 |
enterprise level things that we need. |
