I installed Slitaz on my USB. However I can't figure out how to make it persistent automatically. There are different sources telling me different ways to make it persistent.

One told me to add "slitaz home=usb" to the syslinux.cfg file like this:

append initrd=/boot/rootfs.gz rw root=/dev/null vga=normal autologin slitaz home=usb

but it didn't work for me.

http://www.slitaz.org/en/doc/handbook/liveusb.html gave an example of how to do it manually but I didn't try it and I also want it to happen automatically.

custompc.co.uk/features/602451/make-any-pc-your-own-with-linux-on-a-usb-key.html is an older article that also explains how to make the USB persistent but I don't want to try it cause it looks outdated (from 2008)

does anyone know the best way to make the USB automatically persistent?
