Tiny Core Linux persistent home directory

I have a command line **frugal** install of Tiny Core and I want to have a **persistent home directory**, because the programs I run save results there. I read the persistent option details and followed these instructions . Already added the home=UUID="xxxxxx" boot option to the /mnt/sda1/tce/boot/extlinux/extlinux.conf file and saved it with filetool.sh -b. During the boot process the home=UUID part is printed to the console, the extlinux.conf file stays persistent, but when I create files in the home directory, they disappear after reboot. Is there any way to make this work? If the system stops accidentally, will these permanent files remain there with the latest content, or the system saves them only on shutdown? I also thought about creating a cronjob and execute backup script in every n minutes, but this is the last solution I would like to have.
