append initrd=/live/initrd1.img boot=live config live-config.hostname=portable live-config.username=zeroblock live-config.user-fullname=zeroblock live-config.timezone=Asia/Taipei persistent quiet

up there is my live.cfg option which I set it auto boot-up when system go to boot menu.

I have google like few hours about change live-config.username or live-config.hostname or else but after I make the boot-up option like this, when I login crunchbang , it still restore(?) to default.
Also can't find where to change default "live" password.

Is something I setting it wrong? or much else I have to work on live.cfg.

waiting for big hands <3
