=== Update Kernel === | |||
Add tesing repositories to /etc/apt/sources.list: | |||
deb http://repository.maemo.org/extras/ fremantle free | |||
deb-src http://repository.maemo.org/extras/ fremantle free | |||
deb http://repository.maemo.org/extras-testing/ fremantle free | |||
deb-src http://repository.maemo.org/extras-testing/ fremantle free | |||
apt-get update | |||
apt-get install kernel-flasher-maemo kernel-modules-maemo | |||
cross your thumbs now.. (you backed up before right?) | |||
reboot | |||
WELCOME TO YOUR UPDATED SYSTEM THAT SUPPORTS UNIONFS \o/! | |||
=== Create unionfs / chroot overlay filesystem for development === | |||
Create a 2 GB file on /home/user/MyDocs/sandbox/fs.img | |||
mkdir /home/user/MyDocs/sandbox/ | |||
cd /home/user/MyDocs/sandbox/ | |||
dd if=/dev/zero of=fs.img bs=1M count=1 seek=2048 | |||
mkfs.ext2 fs.img | |||
Get the shiny overlay/chroot shellscript | |||
wget http://metalab.at/wiki/images/d/d8/Chroot-unionfs.sh '''WARNING the link might be different now look here: [[Bild:Chroot-unionfs.sh]]''' | |||
mv chroot-unionfs.sh /sbin/chroot-unionfs | |||
chmod +x /sbin/chroot-unionfs | |||
This script doeas some magic including | |||
* loading the dm-loop kernel module (for /dev/loop? devices) | |||
* overlaying the unionfs filesystem | |||
* mounting all needed filesystem folders inside the unionfs | |||
* chroot()'ing inside | |||
It is started like this: | |||
bash /sbin/chroot-unionfs -v -t /home/user/MyDocs/sandbox/fs.img | |||
Read the source to find out about command line parameters like -t for testing and others.. | |||
If this script is successful you should find yourself in a chrooted environment inside the unionfs | |||
touch /CHROOTED | |||
ls /CHROOTED # it should be here! | |||
exit | |||
ls /CHROOTED # it should be gone! | |||
