About BusyBox

BusyBox it is the main tool in the fight against the violation of the GPL in the firmware. Organization Software Freedom Conservancy (SFC) and Software Freedom Law Center (SFLC).

At the same time, the author of BusyBox strongly opposes such protection, considering that it breaks his business.

For manufacturers who do not want to open the source code of the modified components, in the context of the Toybox project, an analog of BusyBox is being developed, distributed under the BSD license (clause 2). By capabilities, Toybox is still behind BusyBox.

The modular nature of BusyBox makes it possible to form a unified executable file containing an arbitrary set of implemented utilities in the package (each utility is available in the form of a symbolic link to this file).

The size, composition, and functionality of the utility collection may vary depending on the needs and capabilities of the integrated platform for which it is being assembled.

The package is self-sufficient, with a static compilation with uclibc, to create an operating system on top of the Linux Kernel, you just need to create multiple device files in the / dev directory and prepare the configuration files.

    Busybox is too dangerous ... even a smtp server has it for what? The worst thing is that many distros put pressure on it as a primary dependency of the system ... which reveals their intentions to plant the necessary tools for the crime ... eyes to see that he sees and whoever does not know what he says, let him pass by ... will be happier.
