First, and before anything else: it can be done. You will have to deal |
| 34 |
with issues that are perhaps a bit more complex than the usual conflicts |
| 35 |
and issues that show up once in a while even on a stable system which is |
| 36 |
updated frequently. But it's definitely not impossible. |
| 37 |
|
| 38 |
The biggest hurdle in your case is that you need to update tar. Do what |
| 39 |
was already mentioned elsewhere in the thread, fetch the older EAPI 5 |
| 40 |
ebuild, put it in the local overlay and let portage grab that. |
| 41 |
|
| 42 |
If you're lucky, that might be the only problem you'll have. If you're |
| 43 |
not so lucky, you will have a couple packages that were since removed |
| 44 |
from the tree, and which must be either uninstalled or added to a local |
| 45 |
overlay and adjusted as required. (Because they might depend on older |
| 46 |
versions of other packages which do not exist anymore.) |
| 47 |
|
| 48 |
You will probably find some actual bugs too, for example, some packages |
| 49 |
may fail because their dependencies are not correct. |
| 50 |
|
| 51 |
When was the last time this system was fully updated/upgraded? (Not the |
| 52 |
last time you synced the tree, but the last time you did |
| 53 |
emerge -DuN world or the like.) This might be useful to figure out which |
| 54 |
issues are you going to find. |
| 55 |
|
| 56 |
Some recent issues were a change in the C++ ABI and the build system |
| 57 |
change in certain X11-related packages that pulls python3 as a build |
| 58 |
dependency. |
