Ok, I got your points Amro, I want to ask few questions here, I hope these are not irrelevant. In spite of extra storage, hardware compatibility issues and many extra features like you mentioned hot-swapping capabilities.

1) Do all these UNiXES & GNU/LINUX differ at kernel level? Suppose if a small business wants to go for some standard solution like:

File Server, Domain Name Server, Mail Server or Web Server. Should they go for a commercial version or Fedora or any other free availble UNIX flavor will fulfil their requirements, because I dont see any difference

2) Does UNIX & GNU/LINUX kernel differ or Linus Torvald inherited same code from UNIX kernel or he designed his own code, I really dont know about that.

3) If original UNIX kernel code was written at Bell Labs then from where these free UNIX distributions have been evolved? Did they distribute their code to different Universities and organizations? Like BSD?

4) One stupid question, what was the first shell to interact with UNIX kernel, was it sh? or how inventors of UNIX and other experts were interacting with UNIX kernal during initial days?

Waiting for your valuable comments.

Regards,
Tayyab

NAME

       install-solaris - install the Solaris operating system

SYNOPSIS

       install-solaris

       install-solaris	invokes  the  Solaris  Install	program. Depending on graphical capability and available memory at the time of invocation,
       install-solaris invokes either a text-based installer or a graphical installer.

       The following minimum requirements for physical memory dictate which features are available during installation:

       For SPARC machines:

       128 MB

	   Minimum physical memory for all installation types

       128 MB

	   Minimum physical memory required for windowing system

       384 MB

	   Minimum physical memory required for graphical-based installation

       For x86 machines:

       256 MB

	   Minimum physical memory for all installation types

       256 MB

	   Minimum physical memory required for windowing system

       512 MB

	   Minimum physical memory required for graphical-based installation

       In some cases, even if the minimum physical memory is present, available virtual memory after system startup can limit the number  of  fea-
       tures available.

       install-solaris	exists	only  on  the Solaris installation media (CD or DVD) and should be invoked only from there. Refer to the  for more
       details.

       install-solaris allows installation of the operating system onto any standalone system. install-solaris loads the software available on the
       installation media. Refer to the  for disk space requirements.

       Refer to the  for more information on the various menus and selections.

       See attributes(5) for descriptions of the following attributes:
