I believe the second scenario would need /dev/mem access making it a
larger change than it first appears (config with a new option could
possibly save the original kernel file and compare the two kernel
files).
-u Check to see if the kernel configuration was modified
at boot- time (i.e. boot -c was used). If so, compare
the running kernel with the kernel to be edited
(infile). If they seem to be the same, apply all
configuration changes performed at boot. Using this
option requires read access to /dev/mem, which may be
restricted based upon the value of the kern.allowkmem
sysctl(8).
