<p>Gentoo has discontinued support for JabberD 2.x and recommends that
|
|
|
|
|
|
users unmerge the package:
|
|
|
|
|
|
</p>
|
|
|
|
|
|
|
|
|
|
|
|
<code>
|
|
|
|
|
|
# emerge --unmerge "net-im/jabberd2"
|
|
|
|
|
|
</code>
|
|
|
|
|
|
|
|
|
|
|
|
<p>As an alternative, users may want to upgrade their systems to use
|
|
|
|
|
|
net-im/prosody instead of net-im/jabberd2.
|
|
|
|
|
