161 | That alone, however, is not sufficient. Gentoo's networking init scripts use a |
|
|
162 | virtual dependency called <e>net</e> to inform the system when networking is |
|
|
163 | available. Clearly, in the above case, networking should only be marked as |
|
|
164 | available when <path>net.br0</path> is up, not when the others are. So we need |
|
|
165 | to tell that in <path>/etc/conf.d/net</path> as well: |
