This page details next-generation kernel management features for Funtoo Linux, which impacts the following subsystems:
{{Ebuild
|Summary=ruTorrent is a front-end for the popular Bittorrent client rTorrent
|CatPkg=www-apps/rutorrent
|Homepage=http://code.google.com/p/rutorrent/
}}


* genkernel
rutorrent is a front end to {{package|net-p2p/rtorrent}} and is designed to look like utorrent =D
* kernel ebuilds
* boot-update
* grub


== Experimental Genkernel ==
{{console|body=###i## emerge www-apps/rutorrent}}


Experimental genkernel is being developed in the following branch:
===prereqs===
*Install your web server {{package|www-servers/nginx}}, and get {{package|dev-lang/php}} with the fpm use flag running first.
*you must turn on scgi_pass in the {{package|net-p2p/rtorrent}} config.

{{warning|possibly broken, untested}}


The naming convention for kernels is being changed significantly. Previously, genkernel would install and name kernels, etc. like this:
first figure out what php you're using


<pre>
{{console|body=###i##eselect php list fpm
ninja2 drobbins # ls /boot/*37* -l
[1]  php5.5 *
-rw-r--r-- 1 root root  2284126 Sep 24 11:20 /boot/System.map-openvz-rhel6-stable-x86_64-2.6.32-042stab037.1
###i## eselect php list cgi
-rw-r--r-- 1 root root 59261962 Sep 24 11:29 /boot/initramfs-openvz-rhel6-stable-x86_64-2.6.32-042stab037.1
[1]  php5.5 *
-rw-r--r-- 1 root root  3841152 Sep 24 11:20 /boot/kernel-openvz-rhel6-stable-x86_64-2.6.32-042stab037.1
###i## eselect php list apache2
</pre>
[1]  php5.5 *
###i## eselect php list cli
[1]  php5.5 *
}}


In the new format, kernels will be installed and named as follows:
edit the respective php.ini


<pre>
Edit the open_basedir in
build / # ls /boot/2.6.32.042.037.1-openvz-rhel6-stable-nointel/* -l
/etc/php/fpm-php5.5/php.ini
-rw-r--r-- 1 root root  2283775 Sep 25 23:19 /boot/2.6.32.042.037.1-openvz-rhel6-stable-nointel/System.map
{{file|name=/etc/php/fpm-php5.5/php.ini|lang=|desc=php basedir|body=
-rw-r--r-- 1 root root  3862848 Sep 25 23:19 /boot/2.6.32.042.037.1-openvz-rhel6-stable-nointel/bzImage
open_basedir = /var/www/localhost/htdocs/rutorrent/conf:/var/www/localhost/htdocs/rutorrent/php:/var/www/localhost/htdocs/rutorrent/
-rw-r--r-- 1 root root  100358 Sep 25 23:19 /boot/2.6.32.042.037.1-openvz-rhel6-stable-nointel/config
}}
-rw-r--r-- 1 root root 59239975 Sep 25 23:28 /boot/2.6.32.042.037.1-openvz-rhel6-stable-nointel/initramfs
</pre>


Basically, everything will be inside a directory inside <tt>/boot</tt>. The directory will have the same name as the official kernel name, ie. what <tt>uname -r</tt> outputs when the kernel is running. This provides a unified namespace for both genkernel and the kernel itself. This also means that modules and related kernel things will use the same name, such as:
=== nginx config===
{{file|name=/etc/nginx/sites-available/localhost|lang=|desc=nginx configuration|body=
server {
listen 127.0.0.1:80;
server_name localhost;
access_log /var/log/nginx/localhost.access_log main;
error_log /var/log/nginx/localhost.error_log info;
root /var/www/localhost/htdocs;
index index.php index.cgi index.htm index.html;
autoindex on;


<pre>
        location ~ \.php$ {
build / # ls -l /lib/modules/2.6.32.042.037.1-openvz-rhel6-stable-nointel -d
                fastcgi_pass 127.0.0.1:9000;
drwxr-xr-x 3 root root 4096 Sep 25 23:31 /lib/modules/2.6.32.042.037.1-openvz-rhel6-stable-nointel
include fastcgi.conf;
</pre>
                #fastcgi_pass unix:/var/run/php5-fpm.sock;
        }


This simplifies things and also provides an easy mechanism for applications to determine what particular genkernel kernel is running on the system, which is very useful and basically essential for integrating simple kdump functionality.
          location /rutorrent {
              include scgi_params;
              scgi_pass localhost:5000;
          }
}
}}

first figure out what php you're using 

root #eselect php list fpm

edit the respective php.ini

Edit the open_basedir in /etc/php/fpm-php5.5/php.ini

   /etc/php/fpm-php5.5/php.ini - php basedir
open_basedir = /var/www/localhost/htdocs/rutorrent/conf:/var/www/localhost/htdocs/rutorrent/php:/var/www/localhost/htdocs/rutorrent/

nginx config

   /etc/nginx/sites-available/localhost - nginx configuration
server {
