That 4.14 kernal definitely improved the boot times compared to what I was
seeing and what I posted
here: https://github.com/RobertCNelson/boot-scripts/issues/10
However, I am still getting a boot time of close to a minute (~32 seconds
for both *dev-mmcblk1p1.device* and *generic-board-startup.service*).
# systemd-analyze
Startup finished in 21.569s (kernel) + 37.032s (userspace) = 58.602s
# systemd-analyze blame
32.599s dev-mmcblk1p1.device
31.957s generic-board-startup.service
3.137s systemd-udev-trigger.service
2.602s loadcpufreq.service
2.090s networking.service
1.638s ssh.service
1.542s connman.service

Can anything be done to really trim down the boot time to be not much more
than the kernel boot time? And what does one sacrifice in doing so? A 30
second boot would be great. This 60 boot isn't too bad, either, of course,
thanks for your work on that kernel 4.14.
