If this is just a matter of enabling the kernel module, I'll see if we can include this in 2.3.7.0.

Hm, I have disappointing news: ext4 support wasn't really stable until kernel 2.6.28, but the Foneras run 2.6.21 and 2.6.26. So, I'll not be enabling ext4 support, for risk of destroying people's data.

On the longer term, we could look into backporting the stable ext4 driver, but that's something that needs some more work...

(In [2151]) mountd: Don't try to mount ext4 partitions.

This allows mountd to recognize ext4 partitions, so it can skip trying to mount them and instead report something sensible to the user. Since our kernel does not support ext4 (ext4 suppport wasn't considered stable until kernel 2.6.28), we shouldn't be trying to mount ext4 partitions as ext3 (which was what previously happened).
