Yes, but you might not always agree with portage's decisions, |
| 7 |
and the resolution might be non-unique. |
| 8 |
Although the user might always influence it with /etc/portage/package.use |
| 9 |
it might be better to keep this transparent to the user - therefore, |
| 10 |
I suggested a directory in /etc and not in /var |
| 11 |
(Moreover, a cache would not make sense, since the |
| 12 |
previous decision could always be trivially calculated from /var/db/pkg, |
| 13 |
and the user-selected state of the USE-flag for the corresponding |
| 14 |
package. You could not check the validity of such a cache, since |
| 15 |
you cannot check whether USE or /etc/portage/package.use has changed) |

*Validating* consistency is not time-consuming. Looking for possibilities |
| 21 |
to unset use-flags is a much more time-consuming story. |
| 22 |
If everything is consistent or can easily be resolved, you hardly need |
| 23 |
any backtracking... |
