4MLinux Core is an open source distribution of Linux, a special edition of the 4MLinux operating system designed to provide users with a very minimal environment for creating their very own Linux distributions from scratch.
This is the core edition of 4MLinux, on which all the other 4MLinux flavors are based, including 4MLinux Main Edition, 4MLinux Game Edition, 4MLinux Media Edition, 4MLinux Multiboot Edition, 4MLinux Rescue Edition, 4MLinux Server Edition, and 4MLinux Allinone Edition.
It is used to create all other 4MLinux editions
With this distribution it’s possible to create any Linux-based operating system that can be used as a system rescue CD, for playing multimedia files and games, a capable Web or FTP server using the inetd daemon, or a standard workstation.
The core flavor of 4MLinux usually comes with an LTS (Long Term Support) Linux kernel, the GLibc library, Busybox toolkit. In addition, Gallium3D, Nvidia, and AMD Radeon video drivers can be downloaded from the 4MLinux website.
Distributed as a minimal Live CD with support for 32-bit and 64-bit PCs
It is distributed as a single Live CD ISO image of only 5MB in size. It can be used as-is directly from a CD disc or USB flash drive. To enter the live session, you will first need to set a password for the root (system administrator) account.
After that, you will be able to login into the live environment with the root username and the password you’ve just created. There is no graphical desktop for this 4MLinux edition, as all the necessary tools are command-line based.
Under the hood, we can mention that all the core components of 4MLinux have been compiled under Fedora Linux (x86/32-bit/SMP) with the GNU Compiler Collection (GCC) 4.8.1 compiler application.
All in all, 4MLinux Core is a Fedora-based operating system that can be used by experienced Linux users to create distributions with a minimal set of applications, for a specific target audience.
