It's also useful if a new version of a critical package screws your |
| 14 |
system, like glibc, gcc, python or portage. You can untar the package |
| 15 |
directly into the root filesystem to get a functional system back, then |
| 16 |
use "emerge --usepkg" after to do it properly (otherwise portage will |
| 17 |
think the new version is still installed). |
