This patch implement loading of sysctl config files as described in http://0pointer.de/public/systemd-man/sysctl.d.html

This is a very conveniant way of configuring sysctl option for sysadmin which can drop sysctl config files inside this directory to enable some feature.

Dropping a file like disableipv6.conf inside this directory will disable ipv6 $ cat disableipv6.conf net.ipv6.conf.all.disable_ipv6 = 1

There is atm no package which use this functionnality
