Actually, x15 is an alternative of Hurd rather than a Hurd-related kernel, of course, experimental. I thought Braun has dropped this project few months ago, but I've confirmed this morning, it's updating when he's free. ;-) I don't know the purpose of its design yet. But I think the current Hurd is hard to change its core (GNU Mach) to others without large changes, say, L4. I guess x15 could be a better design, dunno. IMO, GNU as an OS has great flexibility to change its kernel as will. From pure technical perspective, it's very good design if someday we can prove it in industrial way. For now, it's not persuasive yet. Maybe the next step of GNU is not to provide a workable OS anymore, since we've made it, and it became an important part of the industry. According to its design, kernel-free could be a significant feature of GNU, to provide further freedom in technical way. Besides, maybe language-free could be another one, if multi-lang in Guile platform could be finished in the future. kernel/language-free here means users don't have to worry about what kernel/language should they choose, just use whatever they like, or choose it according to the design of their projects. This sounds hard, and it's very hard actually. If we think about this point, the purpose of Hurd and Guile become meaningful in practice, not only "oh it's just interesting, so we continue". So it's worth to consider, IMO. ;-) Comments? -- GNU Powered it GPL Protected it GOD Blessed it HFG - NalaGinrut Fingerprint 77F8 7D5B B425 E505 535E C365 9182 7E28 EE78 E925
