Oh ok... didn't think of that because it was discussed in this thread
Advantages:
- Backup system on flash. If you brick your OS you can use your backup system.
- Faster booting. Jffs2 uses compression, so there is a big overhead which results in slower transfer rates and cpu usage. The filesystem on on your SD card can be ext2/ext3 etc.
- Extends your rootfs and you can install more than 256mb of applications.
- Testing system. Install an application on sd and test it. If everything works you ca finally install it on flash. So you can have a cleaner OS.

So this would appeal more to the developer world rather then just average users. So my original assumptions was correct.

I just did the partitioning again and did not set the active flag. Then I made a vfat and ext2 fs, again. After rebooting and mounting ext2, there is still the same data as before when typing "df" but no visible data. How can I format the partiton?
And there is something very wrong:
Code:/media/mmc2 # mkdir test mkdir: Cannot create directory `test': Input/output error

dusko@dusko-desktop:/etc$ sudo fsck.ext2 /dev/sdd2 e2fsck 1.39 (29-May-2006) Couldn't find ext2 superblock, trying backup blocks... fsck.ext2: Bad magic number in super-block while trying to open /dev/sdd2 The superblock could not be read or does not describe a correct ext2 filesystem. If the device is valid and it really contains an ext2 filesystem (and not swap or ufs or something else), then the superblock is corrupt, and you might try running e2fsck with an alternate superblock: e2fsck -b 8193 <device>
