liveslak: enhance the boot debug a bit.
Some explanation about what the 'debug' boot parameter does:
'debug=1' => enable some strategic pauses during boot while showing 'mount'
and 'blkid' output, so you can scroll back and inspect the proceedings
(just 'debug' also enables level 1).
'debug=2' => enable verbose script execution in addition to the above pause
moments.
'debug=3' => verbose script execution but without the mount/blkid info during
the strategically placed pauses.
'debug=4' => dumps you into a debug shell right before the switch_root.
No other pauses other debugging aids are offered like with levels 1, 2 or 3.
But you can check the health of your Live system before Slackware boots up.
