pgrep wget will tell you if a download is still in progress. It seems |
| 24 |
reasonable to assume that if there is no further output to the log and |
| 25 |
wget is no longer running, portage is no longer downloading files. |
| 26 |
|
| 27 |
Or you could get clever and set FETCH_COMMAND to a script that fetches the file and |
| 28 |
then notifies of completion. |

It can't, any more than portage does. Whether the download phases exists |
| 34 |
successfully or unsuccessfully your Internet connection is no longer |
| 35 |
being used, so you may as well shut down the PC. |
| 36 |
|
| 37 |
You are trying to use portage in a way that was not intended. That |
| 38 |
involves compromises, some work or both. |

Another alternative would be to use a USB to ethernet adaptor on the |
| 41 |
embedded board and connect it directory to your router. |

The word 'Windows' is a word out of an old dialect of the Apaches. |
| 48 |
It means: 'White man staring through glass-screen onto an hourglass...') |
