Maxime Ripard - March 23, 2012, 3:49 p.m.
Since we have now two uncompatible init systems, and we want only one of
them at the same time in use in the rootfs, we need to select a
particular init system. This patch also adds $(PKG)_INSTALL_INIT_SYSTEMD
and $(PKG)_INSTALL_INIT_SYSV hooks that are called when the matching
init systems are selected to install properly the init scripts of the
package.
