So questions and comments are being accepted?
The actual values from the measurements in an appendix
would be helpful. Including the boot time breakdown
for the 8 way.
On your chart, the time saved column is distracting to
me as it is extra data. On the relative percentage column
if it could be kexec/full boot that would make it so that
I wouldn't have to go back to the text to understand the
column. Also on the kernel boot time, I think that you
are talking about the kernel init time. So why not call
it that?
On future and ongoing work.
The crash dump seems to be orthogonal to fast booting. I
would like to see future and ongoing work that applies to
fast booting.
