Setting up a start up script for root command

[verdant <pandixiong@googlemail.com>]

I would like to set up a startup script so that the root command for the kernel i.e. system app trackpad

# trackpad notap

is executed at boot and on sleep wake-up for the ADB trackpad on my Pismo G3 laptop.

My understanding is that using rc.local is deprecated in favour of using systemd?

Or, should init.d be used?
