can i use this to add more space to rootfs?

sorry, no.

Can i resize the home partition (program installation space) more than 2 gigs or it is only for the emmc??

it late and you might have found out but....no

why? home partition can not be unmounted. there is a way to trick it thou but it still dose not achieve what we want (increase home)

Edited:
(I cited wiki, but wiki is changing)

There are easy way to increase size of /opt and decrease size of MyDocs.

/opt is space for installable applications. (It is ext2)
MyDocs is e.g. for camera. (It is fat32)

You need PC with Linux (Live-CD works).

On phone:
Install package backupmenu
(apt-get install backupmenu)
reboot
keep keyboard opened
attach N900 to the Linux computer with USB
press 'w' (for USB Mass Storage Mode)

on PC
do not mount drives, if they get mounted automatically, unmount (optional: after backup)
start gparted with root access
shrink size of fat32 partition called 'Nokia N900'
raise size of ext3 partition called RX-something
you will get warnings:
*changing starting point of boot partition will be fatal (can be omitted, because it is not booting partition)
*Data can be lost when resizing partitions. (Backup!)
It will take ~30 minutes.

On phone: press 'q' (to reboot) and detach USB-cable.
Close keyboard to skip backupmenu.

optional:
on the phone
uninstall backupmenu

It's been a while, but I was wondering if this parted is stable? If so, it might be a good idea to add it to backupmenu. Since backupmenu allows you to boot without mounting /home, you could boot into backupmenu and repartition the internal mmc any way you like from inside the n900 under pr1.3...

Nice! Thanks!

GNU Parted seems to be much simpler than fdisk
I will sure prefer GNU Parted

Again: Thanks!

No problem, lexik! Just hit the Thanks button on the post instead of posting a thanks-message. That way we keep the threads focused.
