Good ext2 reference

[stonedzealot]

I posted on this a few months ago, but that was for a bootloader. Now, I'm nearing the point where I want to start fiddling with implementing a filesystem. ext2 seems to be a good choice, it's well documented and has nice features but I still can't wrap my head around how files are *actually* referenced within a directory. Theoretically, I know, but evidently I'm missing something.

So, anyone have any good ext2 docs aside from those on OSRC (which are the ones that have put me in the current half-knowing state)?

Haven't read it but google has:-

http://e2fsprogs.sourceforge.net/ext2.html
http://e2fsprogs.sourceforge.net/ext2intro.html

Thanks, and I don't want to sound ungrateful, but that's an OSRC linked doc and the e2fsprogs are nice but the source is incredibly confusing (I tried to understand ext2ed with no luck).

i was about to suggest you to look up GRUB's fsys_ext2fs, hoping that it would be simpler to understand than Lx kernel's component, but it appears to be as much confusing at best ...

This is not a good reference, but minirighi implements ext2 fs in read-only mode... unfortunately it is written/commented in italian for now... if you don't find nothing better you can read it into the CVS repository http://cvs.sourceforge.net/viewcvs.py/minirighi/minirighi/fs/ext2/ or download the source code from the sf site http://sourceforge.net/projects/minirighi

Wow that should be good, maybe I'll pick up some Italian on the side =) . Anyway, despite the Italian commenting it will probably be much more straight forward than Linux or e2fsprogs's ext2ed. Thanks alot, I'll check it out when I get home.
