I know that, in general principle. But it's a test environment. I'd |
| 19 |
assume stricter standards of "purity" there than elsewhere. simply |
| 20 |
going by changed-use can break some library dependencies. We need to |
| 21 |
use depclean to remove build deps junk after the emptytree, and we're |
| 22 |
revdep-rebuilding twice in case the depclean borked something. (To be |
| 23 |
really strict, revdep-rebuild should be repeated until it stops |
| 24 |
building things...) |
| 25 |
|
| 26 |
Heck in some setups empty-tree will simply fail thanks to circular |
| 27 |
deps of the global use flags and you'll need manual intervention to |
| 28 |
bootstrap a package with less USE... |
