OT for the original question, but there is a way to lessen the amount of work |
| 22 |
done if a package may need to be merged (or attempted to be merged) |
| 23 |
repeatedly. You have to do it manually though: |
| 24 |
|
| 25 |
- ensure all needed deps are already installed |
| 26 |
- ebuild <package> <command> |
| 27 |
|
| 28 |
where <command> is on of fetch, unpack, compile, install, etc as detailed in |
| 29 |
the ebuild man page. You can't restart a failed compile from where it left off |
| 30 |
[you can do that if you are running make manually, but ebuild abstracts that |
| 31 |
away] but at least some work can be omitted. |
| 32 |
|
| 33 |
If course, this in no way answers the original question, but it's occasionally |
| 34 |
useful to know |
