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
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
