Right. That sound more sensible. I would expect no change if the
boot is IO bound and not CPU bound, but slower boot with concurrent
booting was a mystery to me. :)
Was this with or without dependency based boot script ordering? The
concurrent booting only work with dependency based boot sequencing.

Please do, I find it interesting to learn more how different Debian
systems boot to see if there are new improvements to be found. :)
