However, this C program (in compliance with the LSB) assumes the use of runlevels. This operating system uses the init daemon of BusyBox, which <a href="http://git.busybox.net/busybox/tree/init/init.c?id=3da46c81#n1221">doesn't support runlevels</a>.

It is currently being <a href="http://wiki.debian.org/Multiarch">documented and implemented</a> in Debian and Ubuntu.

It can be used for building packages (see "Package Cross Building Tool" below) or installing the operating system on hardware targets.</p> <p>Basically, the tool would fetch from the package archive the index of packages, determine which packages need to be installed, download each package, and unpack each package. Since the package manager may not be available, the tool must handle dependency resolution and package unpacking on its own.</p> <p>We can't use debootstrap, since the formats of our binary packages and package archives differ slightly from those of Debian. But we can model our tool after debootstrap or even just fork debootstrap.</p> <h2 id="pkg-x-build-tool">Package Cross Building Tool</h2> <p>A tool similar to pbuilder and sbuild of Debian needs to be written to build packages within a chroot environment containing a base system installed by the installation bootstrap tool.
