Usage

The unionfs driver must be loaded before attempting to create any union mounts. To load the driver, execute the following command:

 

/sbin/insmod /usr/lib/modules/2.4.17-uc0/unionfs.o

using /usr/lib/modules/2.4.17-uc0/unionfs.o

 

After successfully loading the module, you can remount directories in stacks. To make your /etc writable with a ram overlay, try:

 

mkdir -p /mnt/etc

mount -t ramfs none /mnt/etc

mount -t unionfs none -o dirs=/mnt/etc=rw,/etc=ro /etc

 

To add or change files in /bin, you could use:

 

mkdir -p /usr/rootbin

cp /usr/mytest/dvdplayer.bin /usr/rootbin

mount -t unionfs none -o dirs=/usr/rootbin=rw,/bin=ro /bin

 

To add files in /usr/bin to /bin, extending the number of available commands, you could use:

 

mount -t unionfs none -o dirs=/usr/bin=rw,/bin=ro /bin

 

For skinning, you could use an HDD mount to mount over /img:

 

mount -t unionfs none -o dirs=/usr/img=rw,/bin=ro /img
