I just don't think Puppy uses run levels or knows what they are.
Here is Puppy /etc/inittab, what do you think?
tty1::respawn:/sbin/getty -n -l /bin/autologinroot 38400 tty1
tty2::respawn:/sbin/getty 38400 tty2
Fortunately for me, I have a DVD/CD-ROM drive.
If Puppy won't work as the host operating system to 'install from iso', and given Lifebook's computer, I wonder what to do? I suppose wait for Lifebook to come back with an update or report.
