Did you test different boot-time of standard stripped-down distros,
before setting this up, or did you go straight there because there is no
hope to significantly reduce the boot-time (read "time before live-view").
Said otherwise : what is the cost of the lasts seconds saved on booting,
and is it worth the effort for us average hackers ?
IIRC, a base install of a standard Debian boots in 15 seconds (from the
BIOS to the prompt, VIA C3 1Ghz). You have quite nothing for this time,
but it is still really low.
