Oh, this was discussed so many times already... There is NO single |
| 14 |
correct solution to such problems. And some mathematically correct |
| 15 |
solutions are impractical (e.g. half of the tree rebuild), so other |
| 16 |
ones which are good enough are preferred. As long as imperfect |
| 17 |
solution works fine, I'm ok with it. |

As for paludis, I tried it. Everything mentioned below is my |
| 20 |
_personal_ experience and not supposed to pretend to be objective. |
| 21 |
So, from my experience paludis turned out to be: |
| 22 |
|
| 23 |
- slower then portage (I don't care here if it is more correct or |
| 24 |
not, I just want to do my daily job); |
| 25 |
|
| 26 |
- not fully compatible with portage: it triggers a lot of problems |
| 27 |
portage doesn't. While this may be good for QA and tree |
| 28 |
improvement, I don't want to hang my workflow due to these issues; |
| 29 |
|
| 30 |
- importare instead of local overlay is a complete nightmare: |
| 31 |
usually I don't want to install package exactly as make install |
| 32 |
does: often it lacks some required files (e.g. init scripts) or |
| 33 |
installs something unneeded on Gentoo system. |
| 34 |
Besides I use local overlay to test packages before committing to |
| 35 |
public overlays or Gentoo main tree. Lack of local overlay support |
| 36 |
is sufficient to send paludis straight to waste bin on my systems. |
| 37 |
|
| 38 |
- completely insane command line options, arguments required to do |
| 39 |
what I want to do are quite cumbersome, portage is much saner here. |
| 40 |
|
| 41 |
Everything above is just my personal experience, so your mileage |
| 42 |
may vary. But after all that issues I don't even want to try |
| 43 |
paludis in the foreseeable future. |
