Just wondering, is there some relatively easy method to repartition the whole thing? If I wanted to say use 16 Gb for rootfs and opt or something, are there limitations to this? How would I go about doing that?

EDIT to make sense

I think the limitation there is that the rootfs and the 32 GB flash are on differerent flash chips. The rootfs one being tiny and fast.

Are we sure about this or is it just speculation?
If yes then the way to go would be to have a big opt then i suppose. hmpf. Not really what I wanted to hear. Either way, reparitioning the opt should work without reinstalling anything as long as it's empty, and the rest is empty, right?

As of now, /opt is a symlink to /home/opt which resides a 2 GiB partition. /home/user/MyDocs occupies the rest of the 32 GB (note that this is GB, not GiB).

This is what sfdisk -l shows:

This is the 32 GB flash:
Code:
/dev/mmcblk0p1   28 GB FAT 32
/dev/mmcblk0p2   2 GB Linux
/dev/mmcblk0p3   768 MB Linux swap
/dev/mmcblk0p4   Empty
I can't ssh into the device right now at work, so I can't copy&paste the sfdisk -l output. Maybe someone else can. I don't see the rootfs here. But you can see from the output that it's not on the internal 32 GB flash.

Yes, of course, just like you would do it on any other linux machine /opt should be a filesystem with unix permissions (currently ext3?), /home/user/MyDocs is fat32 and is exported over USB.

Once I get the device I definitely plan to play with this a lot (i.e. repartition, move whole system to eMMC, boot from microSD).

Nice to see the swap there at least, so you can resize that if needed. I wonder how much slower it would be to have everything on the 32GB flash.

It would be great if anyone with device would care to update http://wiki.maemo.org/Nokia_World_2009_QA#Maemo_5 (the 'output of' part)

Heck, I would love to get N900 firmware image, that would answer me a lot of questions :-)

It's not speculation. It has been discussed on the PyMaemo and maemo-developers mailing lists. It was re-mentioned by Marius Vollmer (a Nokian) at the /opt BOF at the summit.

One thing which was suggested was putting swap on the fast, 256MB chip and the whole rootfs on the eMMC (32GB, partitioned into both VFAT and ext3).

And the opt and home partitions can be resized as one wishes, amIright?
Correct.
