Re: Repartition the internal drive

Well I've done it... only had to reflash 3 times...
This is just stupid but if MyDocs isn't vfat nothing seems to want to work. This shouldn't be so - I would consider this a bug but not sure if Nokia would or the Maemo team.

Here's the file I made:
And of course THIS CAN MAKE IT A BRICK SO BE PREPARED TO RESTORE FROM FLASHER OR ANY OTHER WAY YOU CAN THINK OF
cat repart.sh

Code:

#!/bin/bash



echo "Not for running only REFERENCE!!!"

exit

BEWARE: if you mess up in any single step, you'll brick your N900, and will have to reflash, so not for the meek. You're on your own.

But I did it this way, so it works.

If I don't want to partition right away, could I without problems just do this part:

Code:

   cd /usr/share/

   for FILE in fonts icons locale mime nokia-maps pixmaps sounds themes tutorial-applet zoneinfo

      do

      mv $FILE /home/root/usr/share/

      ln -s /home/root/usr/share/$FILE /usr/share/

      done

If this is ok and doesn't cause any speed issues, it would at least give me some extra MB in / to play with.

Re: Repartition the internal drive

Yeah. you can do that.

Re: Repartition the internal drive

Thanks a lot for your fast reply! I have now done it and so far everything seems to work fine :)

Re: Repartition the internal drive

I just used an extra microSD (4GB) to build my own Debian lenny chroot. I think it's not good to mess with the disk layout of the N900. So using a chroot on extra microSD you don't have any limitations beyond the microSD and don't loose any functions, such as regular firmware updates. You also can use multiple chroots on your microSD, so you are also able to install http://repository.maemo.org/stable/fremantle/armel/.

Re: Repartition the internal drive

Can you upload your debian rootfs somewhere?

I've had a go at making it with debootstrap, but didn't quite get it done yet...

Anyway found out a few other bits like don't change passwd to use a diff shell. Seems to just break it and so on.

I need to fix those instructions I've posted.

Re: Repartition the internal drive

so ruskie when you do df -h, what do u get?

Re: Repartition the internal drive

Ok, I'm just going to post a couple things here as my 5401st post :)

First, I have a package called "easy-chroot" in the Extras-devel repository. This lets you chroot into either an image file or a partition, and it mounts all the right things so that you can share everything with the main Maemo system. You can use Easy Debian as a slick wrapper on this system. You can chroot in as root or user, too.

Secondly, I have a bunch of rootfs stuff in qole.org/files, including a debian rootfs (for dumping into a partition), a 1.3 GB debian rootfs image (for putting in MyDocs), and a development sdk rootfs image.

I have repartitioned a "class 6" microSD card, and then used my new ext2 partition as a chroot, but it seems quite slow, no faster than using an image file in MyDocs. That concerns me. I'm waiting for more hacker types to report back after experimenting... Is the microSD slot really slow? Is it just my card?
