creating a folder or file

[jonathancagua]

I have problems creating a file, I get the following message.

[@Linux root]#mkdir jc mkdir: can't create directory 'jc': Read-only file system [@Linux root]#

The rootfs is squashfs, it is read only in RAM, you can't write to it. (But you can use tmpfs to do modifications, but they will stay only in RAM)

I was able to create a file but it would be in the volatile.

[@Linux root]#cd /var/volatile [@Linux volatile]#cat > test2.sh

!/bin/bash

echo "hola mundo" [@Linux volatile]#cat test2.sh

!/bin/bash

echo "hola mundo" [@Linux volatile]#sh test2.sh hola mundo

Is there any way to save it permanently? Since I want to do driver test and then add with: sudo insmod hello_world.ko
