<hr />
<div>I found it is possible to add a partition to the internal flash card.<br />
<br />
== WARNING: Using this recipe you will lose MyDocs. ==<br />
Make a backup of MyDocs!<br />
<br />
= Creation of the new partition =<br />
umount /home/user/MyDocs<br />
<br />
/home cannot be umounted, unfortunately. But this didn't do any harm to /home<br />
<br />
Use parted to shrink the MyDocs partition (on my N900 it was the 1st one)<br />
parted /dev/mmcblk0 print<br />
parted /dev/mmcblk0 1 resize 1kb 25GB<br />
<br />
reboot<br />
<br />
Use fdisk to <br />
# remove the first partition (Because parted makes it not end on a cylinder boundary)<br />
# recreate the exactly same partition again (this time ending on a cylinder boundary) Make sure to specify "TYPE C" for vfat<br />
# add the 4th partition right after the 1st one<br />
<br />
reboot<br />
<br />
Enjoy the new partition.<br />
The result might look similar to this one<br />
Disk /dev/mmcblk0: 32.0 GB, 32015122432 bytes<br />
4 heads, 16 sectors/track, 977024 cylinders<br />

== Using the new partition == <br />
Using bootmenu.sh you can in fact boot from that partition. <br />
(I got bootmenu.sh via svn from https://garage.maemo.org/plugins/scmsvn/viewcvs.php?view=rev&root=bootmenu&revision=53 using trunk/install_bootmenu) <br />
<br />
Copy the stuff of your root dist to the new one<br />
rsync -rlutopgxv / <mountpoint of new partition><br />
<br />
Copy the device tree (Sure this is too much, but not copying it will not work)<br />
cp -af /dev/* <mountpoint>/dev<br />
<br />
Using bootmenu.sh and this entry in /etc/bootmenu.d I can now boot into my new 3.7GB root drive<br />
