URLMount and custom file systems
by Andre-John Mas 17 Jan '07

site_archiver(a)lists.apple.com Delivered-To: darwin-dev(a)lists.apple.com Hi, I recently downloaded http://code.google.com/p/macfuse/ and reading the documentation it would appear that the necessary API needed for using URLs to refer to filesystems is a private. This means that if I wish to use sshfs I need to use the command-line. I few questsions: - are there any plans to make the necessary API public? - is there any reason why this functionality is not made part of filesystems, instead of being registered in a separate folder?

However, since this is simply a means of tracking allocations, it's probably not what you're thinking of. I don't think that F_ALLOCEXTSPACE does what you think it does, but if all you mean is that you want a single contiguous slab of disk space at an offset within a file, you want F_PREALLOCATE which is documented in fcntl(2).

(strange this information is pretty hard to find on the apple website itself). Is there a way around this? Recompile the kernel? Cheerio! Kr.

Re: Darwin installation on i386 PC. darwin8.0.1 vs. opendarwin7.2.1

site_archiver(a)lists.apple.com Delivered-To: darwin-dev(a)lists.apple.com User-agent: Thunderbird 1.5.0.9 (Windows/20061207) Kristoff, Gegroet, About a month or two ago, I got myself a second-hand PC to "play around" with all kind of operating-systems on it. As I already tried out darwin, opendarwin and gnudarwin on my old G3 imac-computer about a year ago, I descided to give the i386-versions of it a try on this new box. However, sofar, I have not been able to install darwin on it. Opendarwin 7.2.1 for i386 does install and work without much problems (I did have some problems to get GRUB configured correctly as the OS is installed on a disk on the slave controller); but darwin8.0.1 does not not work. I downloaded "darwinx86-801.iso.gz" and burned it onto a CD. I am able to boot and it goes as far as "The following devices are available for installation:" but then it stops. This is on a pretty standard PC without any exotic hardware, with a 1 Ghz pentium III and 512 MB of RAM. It does have two disks but none of them appears in this list. The strange thing -as I already said- is that it does work OK with opendarwin 7.2.1. Anybody any ideas? It is possible to add any "debuging" options to see what exactly is going on and what is causing the installation-process to halt there? I would like to be able give darwin itself a try as I noticed (in the more then a year that I haven't watched darwin anymore) that the opendarwin project now seams to have stopped. Is there absolutely no developement on opendarwin anymore? And there doesn"t seam to have happend that much on the "gnu-darwin" side neither; that since 2004. (now more then 2 years ago)? So is there still any work done on using darwin as a basis for an alternative OS? GNU darwin did already provide some part of this. On the same computer now running darwin, I have now less then 3 other operating-systems installed and running which are based on debian with a non-linux kernel: - debian/kfreebsd (GNU debian with a freebsd kernel) - debian/hurd (GNU debian with the hurd kernel) - nexenta (GNU debian with a opensolaris kernel) (althou this OS is not a "official" branch of debian). So, the only one that seams to be missing is GNU debian with a darwin-kernel! Cheerio! Kr. Bonne. _______________________________________________ Do not post admin requests to the list.
