They even use the same L4 microkernel family. As a non expert on microkernels in general, I was wondering if anyone could point out the differences between the two. Or even expound upon the benefit of ruining the Linux kernel in a user mode virtual machine on top of a micro kernel.

http://genode.org/documentation/general-overview

and i presume that the developer would prefer not to run linux on top of l4 if they had a similar rich userland available for l4.

an older demonstration of an l4-based secure os from the same people (?) is tu:dos:

live-cd:

there is also a simple live-cd of genode running on l4/fiasco: http://genode.org/news/download/live-cds

doesn't do very much, but is still impressive for an 2,8 mb iso.
it seems to me like genode is just a further developed tu:dos? Wed, 27 May 2009 15:24:00 GMT donotreply@osnews.com (puenktchen) Comments RE[2]: Like Hurd but with momentum? http://osnews.com/thread?365664 http://osnews.com/thread?365664

You have a wandering colon (probably treatable with medication). The project was tud:os, as in Technische Universitaet Dresden Operating System.

Darn, I was hoping it was another version of DOS to play with. GUI's are for WIMP's ;} Wed, 27 May 2009 15:32:00 GMT donotreply@osnews.com (fretinator) Comments RE: Like Hurd but with momentum? http://osnews.com/thread?365666 http://osnews.com/thread?365666

no any more:

"By now, the development of Hurd/L4 has stopped."

another dead end for the hurd. so they are still using the mach-kernel. but i don't think that this is their major problem.Edited 2009-05-27 15:50 UTC Wed, 27 May 2009 15:47:00 GMT donotreply@osnews.com (puenktchen) Comments RE[2]: Like Hurd but with momentum? http://osnews.com/thread?365676 http://osnews.com/thread?365676 Oh right, I forgot about that.

I know enough to know the differences between monolithic and microkernel design. Wed, 27 May 2009 16:49:00 GMT donotreply@osnews.com (Bill Shooter of Bul) Comments Looks nice http://osnews.com/thread?365680 http://osnews.com/thread?365680 Now this is kind of impressing what these guys are doing. Not quite sure yet "why" they are doing it ;) . As I understand having a choice between kernels and solid API on top of it would allow developers to:

1. write applications that will run ok on all these kernels
2. choose kernel that suits best for given hardware platform/task
3. provide nice abstraction layer for hardware etc.

Wasn't POSIX all about that? ;) Wed, 27 May 2009 17:11:00 GMT donotreply@osnews.com (kajaman) Comments RE: Like Hurd but with momentum? http://osnews.com/thread?365682 http://osnews.com/thread?365682 When viewed from 10,000 feet, both projects share the same goal of building a microkernel-based multi-server operating system. But the intentions and approaches are very different. Hurd started with the goal of becoming a more flexible and secure Unix. Therefore, POSIX compatibility was regarded as prime objective. However, as explained by Neal Walfield and Marcus Brinkmann in their insightful paper "A Critique of the GNU Hurd Multi-server Operating System"

http://www.walfield.org/papers/200707-walfield-critique-of-the-GNU-...

this undertaking turned out to be extremely complicated, in particular because of legacies inherited from POSIX. In contrast, Genode disregarded POSIX compatibility for building the foundation of the system and instead went for an API that is as minimalistic as possible but still allows to build complex sub systems on top. This turned out to be the key for the extremely low source-code complexity of its base system.

Even though Genode does not regard POSIX as a first class citizen, POSIX compatibility remains an essential feature to allow the reuse of existing applications until native Genode applications become available. For this reason, a POSIX execution environment and/or virtualization solution became part of the road map. But POSIX will be provided on top of the OS rather than being the foundation of the OS.

Genode is somehow related to TUD:OS. Back in 2006, the main Genode developers had been responsible for the TUD:OS demo CD available at http://demo.tudos.org. However, Genode was built completely from scratch, taking the experiences made with TUD:OS into account. Today there is (unfortunately) no connection between both projects.Edited 2009-05-27 17:24 UTC Wed, 27 May 2009 17:22:00 GMT donotreply@osnews.com (nfeske) Comments RE[2]: Like Hurd but with momentum? http://osnews.com/thread?365745 http://osnews.com/thread?365745 They are developing viengoos Thu, 28 May 2009 07:31:00 GMT donotreply@osnews.com (fithisux) Comments RE: Full track download http://osnews.com/thread?366337 http://osnews.com/thread?366337 RE: Full track download
