SVR4 Packages Available for Solaris 10 Containers

Jerry Jelinek recently posted SPARC and x86/x64 SVr4 packages on the Solaris 10 Containers project page. The packages contain the binaries that allow administrators to create and manage Solaris 10 Containers. (See this post for information about Solaris 10 Containers.) As of this writing, the packages are synced to ONNV build 118 and should be able to manage Solaris 10 Containers running S10U7.

Please feel free to download and use the packages. However, please note that the technology behind Solaris 10 Containers is still in development. The binaries in the packages represent the technology as it currently stands.

Please send us any comments that you might have via the zones discussion forum on OpenSolaris.org. Any feedback you can provide regarding bugs would be especially welcome because it would help us discover behaviors that will require emulation. :)

The Best Way to Learn Kernel Programming Is to Do It Yourself

I want to contribute to an open-source operating system in order to broaden my understanding of operating systems and make my mark in the F/OSS community.  The three biggest contenders in my mind are the OpenSolaris OS, the Linux kernel, and the FreeBSD project.  I don't think I could go wrong choosing any of them, but I decided that spending time learning how the kernels work and trying to navigate the source trees would be a waste of time.  So I concluded that if I want to learn about operating systems on the lowest possible level, then I should construct a kernel for fun.

Following my tradition of sticking 'KANE' into my project names in honor of Kane from the Command & Conquer series of video games, I have decided to name my new kernel KANEOS, the Kick-Ass New and Expeditious Operating System.  I'm not quite sure what I'll put into it, but I'm looking at targeting 64-bit x86 extensions and multitasking.  It'll be fun to write a small kernel that provides a basic standard C library.  (Of course, I'll continue to contribute to OpenSolaris.  :-D )

I found a couple of websites that might be helpful for amateur kernel hackers like me:

Typing "osdev" into Google search yielded a fair number of OS developer sites, including the ones above.

I'm sure that I'll be in for a long but profitable experience.  :-) 

About

I am a kernel developer at Sun Microsystems, Inc., working on zones and resource pools. This blog logs some of my thoughts regarding my work and the [mis]adventures that I have while working on Solaris.
