Ext4 filesystem support for MacOSX
i've been searching around if already someone did a kexts in order to add MacOSX support ext4 new filesystems available for linux, and nothing found, i would like to make a try, or at least start the digging for it.
Actually i'm using ext4 on my root linux partition, and ext3 (too lazy, too slow) on my home partition so i can read it from MacOSX, but i would love to move all my linux partition to ext4 which really improve the experience. so the theme is open, i'm hearing any suggestion before start developing.....

i think maybe that could help. I've been reading around, and so far i could decide for develop a new kext that support ext4 filesystem, or some user-space app that manage the filesystem.
My point now is: It matters that i use Voodoo kernel instead of Vanilla one for this " kernel development" purposes? CPU: Intel Pentium Dual E2140 1.6 GHz. Graphics: Intel(R) 82945G (128 MB).

They all work identical for FS handling so... Apple's HFS and FAT drivers are also opensource and available from: http://developer.apple.com/opensource They should provide a good insight of how Apple builds their FS drivers |

Wow. You like the bleeding edge. I haven't moved to ext4 yet-- scared away by some of the early 0 byte bugs...
Anyway, I'd second the suggestion of FUSE. I've been using FUSE with ntfs-3g and had very few problems. Plus the abstraction of a filesystem is reasonable to work with, unless you really want to learn IOKit. You could even start with http://sourceforge.net/projects/ext2fuse project (but you'd have to make the code 64-bit, to add in all the changes in ext4). -- MacBook Pro - have allergy to nickel in the aluminum casing.

I already start to learn IOKit, and tried to study the code of the ExtFSManager from sourceforge.
Just check that project, ohh men, that simplyfies the work a lot. I'll check that. I've been a little off to this, because of my real work, but as soon as i can install on my laptop, develop start CPU: Intel Pentium Dual E2140 1.6 GHz. Graphics: Intel(R) 82945G (128 MB).

ext4 not ready for prime time
I'd be wary of ext4, at least until some of the fixes stabilize:
