If you don't like useless conversations, bail now. Is it really an OS at this point? its a kernel executing, which at some point starts loading init scripts. perhaps it could be a kernel feature? 8) While technically an OS anything that can be described as an interface between hardware and user, one could argue where that line in the sand is drawn. I always envisioned an OS as a system of things which make it possible to operate. Most people could not operate with just a kernel and no application (a shell for example). its a kernel feature. hahaha. -g ps - the misconceptions of DHCP and the application of; wow, this is a sysadmin list! 8) On Feb 6, 2010, at 7:42 PM, Ben De Luca wrote: > > On 07/02/2010, at 10:52 AM, todd@sohovfx.com wrote: > >> BOOT_PARALLEL > > > Is a 'new' feature of the operating system and is completely independent of which kernel is being used. > > > > _______________________________________________ > StudioSysAdmins-Discuss mailing list > StudioSysAdmins-Discuss@mailman.studiosysadmins.com > http://mailman.studiosysadmins.com/mailman/listinfo/studiosysadmins-discuss _______________________________________________ StudioSysAdmins-Discuss mailing list StudioSysAdmins-Discuss@mailman.studiosysadmins.com http://mailman.studiosysadmins.com/mailman/listinfo/studiosysadmins-discuss |

Init is?definitely?not part of the kernel, its the last thing the kernel does as part of the boot sequence.? What init does is entirely up to it, and not part of the kernel. Though obviously init runs on top of the kernel, as does every thing else.? Its entirely possible to run any kernel you want with any init you want.? Having init run it scripts as a?dependency?tree rather than a list makes sense given the number of tasks a modern computer needs to run through to fully boot and the changed that have?occurred?with hardware (multi vs faster processor). Some one made the point that does it speed up any thing? Now that your trying to do much more. And I would have to say yes it does, both experimentally and logically. The kernel is a much better?scheduler?of its resources than any human.?

as long as its the same architecture as the hardware (since we are stating the obvious). 8)
to whomever was wondering if doing 2 things at once was faster, if either of these 2 things only consumes 20% of the system resources, yet one has to wait for the other to finish, at any time we are only using 20% of the systems resources. if both tasks will take 10 seconds to finish, you are waiting 20 seconds. if both fire off at the same time and together they consume 40-60%of system resources, they'll both finish in 10-12 seconds typically.. Take this example and add some network voodoo into it: service 1 is waiting for a network resource (say a NTP server) which isn't answering, it may wait 30 seconds or longer for it to time out and decide to move on. during that time you could of been brining up other services which are not dependent on NTP... -g
