| 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!
