Good morning, folks! (At least, it's morning on the east coast of USA)
QUESTION 1: Would someone please explain the /var/run/dmesg.boot excerpt below?
Note: I have glanced at both of the following links, but at the
moment, I do not have time to dig into the documentation and learn all
about this. I'm hoping to get enough knowledge to understand what's
going on with this excerpt, and then later invest time in deeper
learning.

[END output of df command]
QUESTION 2: I'm suprised that the device names (from the df output
above) do not include "ad0s1b" and "ad0s1c". I thought the naming
should follow the model of "ad0s1%" where "%" begins at "a" and
continues in alphabetical order for each partition on that device.
What am I missing?
TIA,
Daniel
