Description:
User-mode Linux (utility programs)
User-mode Linux is a port of the Linux kernel to its own system call interface. It provides a kind of virtual machine, which runs Linux as a user process under another Linux kernel. This is useful for kernel development, sandboxing, jailing, experimentation, and many other things. . This package contains userspace utilities for use with User-mode Linux, including uml_mconsole, uml_moo, uml_switch, uml_net and tunctl.
