Hello,

UNIX has been regarded as the mother of most of the operating systems. Some of the popular members of this family Include :
- System V Release 4(SVR4) developed by AT&T.
- 4.4 BSD From university of California
- AIX from IBM.
- HP-UX from Hewlett-Packard.
- Solaris from Sun Microsystems.
For those who are still confused between Linux being an OS or kernel, Linux in true sense as written by Linus was a kernel that was written by referring to book on Unix internals (Though the Linux kernel has adopted good features from many other Unix like kernels too) while the commercially available distributions that contain utilities like graphical desktop, text editors, compilers etc on top of the Linux kernel are complete operating systems. Linux is a free software (Url 1,Url 2).

Since it is a free software, there are several possibilities considering its developement:
- Point 1: Do you really have to stop using X11 and System V for something else? Of course, Linux and free softwares have to evolve. Drop X11, drop System V! Of course.
- Point 2: However, for non-commercial research purposes, you can keep the Unix tradition and you can still use X11, GCC and vanilla Linux kernel.


Does having a bare Linux not so much nicer than having a Systemd Debian? Do you wish you have a "pure Linux" based on any distribution? In other words, Linux without any distribution. http://unix.stackexchange.com/questi...y-distribution
Making your own system, means to start first with the kernel. The fist thing is to get the vanilla kernel. www.kernel.org.
Classical kernel compiling, make menuconfig , make , makes modules
After getting the vmlinuz, create the initrd.img. Boot it with syslinux or grub, and set it to use Init. You may use the minimal busybox to later build your linux box: http://www.linuxjournal.com/article/4335
The method is fully described here:

Best regards and have fun running your own Linux distro!

Why bother with an initrd? That's really only necessary for a stock kernel. If you're going to build your own, you can build in the root filesystem and boot directly to the hard drive.

You can, with Gentoo, build your Linux straight from source-code (thus, optimized for your CPU type), omit the initrd step altogether (since you know exactly what drivers you need), and configure it exactly the way that you like. Up to and including the init-process.

I had a machine, originally sold with Windows-95 on it when that was new, which could boot into Gentoo Linux in six seconds flat. And, it was fast!

When people carp about "the new ways of doing things," however, I think that they tend to forget that there are millions of Linux installations in service all over the world, and that sometimes a company has to deal with a stable of hundreds or even thousands of them. Suddenly this becomes a very big system infrastructure management problem. Some of the basic things that "systemd" introduced, such as daemons which could communicate with one another and a scheduling system that really understands dependencies among them, really are improvements that are especially important when you've got a lot of machines.

The much-maligned Microsoft Windows system also has a lot of infrastructure-management kit built into it, for the same basic reasons. Or, look at what Red Hat does, deploying an OS that some might say is based on Linux.

>#2: +1! Maybe webresearch: localyesconfig (tinyconfig probably UNuse-ably minimal)

I tried gentoo long time ago, and what you write is actually what I need. Something very fast, however, it won't work much since the today's browser, ... xorg needs pretty a lot and are very demanding on hardware.
