So I wanna get support for reiserfs. On desktops and servers its better for small files. I really don't expect to see much of a performance gain, I'm just doing this for shits and giggles.

I downloaded reiserprogs-armsel from debian.org and it install and ran perfectly. I was even able to format my microsd card reiser fs.

then I rebooted and bricked my phone(microsd is set to automount),

I was using

/dev/mmcblk1p1 /mmc auto 0 0

I'm guessing busybox version of mount don't cut the mustard, and probably a kernel incompatibility(murphies law assume the worst)

Um, did you have a reiserfs kernel module?

I'd exect nilfs2 and LogFS to be much faster on flash than reiserfs..

Better than ext3, but ext3 is old news. ReiserFS is old news (I hope will be removed from the kernel soon). Ext4, XFS, or once Btrfs becomes stable, are your better options.

Of course if all you want to do is brick your device from a file system that dies like how the author treats his wife, then sure, Nokia gives you that opportunity.

ReiserFS never failed me with debian on either desktop or server enivroment. Its faster than ext3, and I've always had problems with XFS and JFS for some reason.

I'm not gonna touch this with a ten foot pole. The story of Hans Reiser is quite tragic, but personal issues weight naught for me in this regard.

I've been doing my reading and it seems that there are different file systems that are designed to work on flash memory on embedded system. could you recommend one thats fast with low power, and easy to installed.

Btrfs will be the end all for all file system needs. It just needs to be a little more mature.

shadowjk mentioned nilfs2 and LogFS, and they are good recommendations. I think they are the only maintained file systems that have flash in mind when they were made. The only problem you'll have is that Maemo 5 comes with kernel 2.6.28 and most of these files systems are designed with at least .30 and higher. You may have to adjust the latest source to compile for .28.

A disk formatted with reiserfs is a time bomb. I have experienced this more than once.

whats the best way to do that on the n900, it doesn't come with gcc or any other sort of recompile tool, is there a package with diffrent file system support or is anyone working on it

There's a thread floating around,Check out this thread, you could probably request a kernel build with the module complied in.

Or you can grab the SDK and built it yourself, I've done it for a handful of modules already.
