The log is a place where all the applications running on the Bytton LTE equipment store their output
messages: status reports, confirmation or error messages, activity, and so on.
It is a plain text (thus easy to interpret) record of actions taken by the software as it runs on Bytton LTE:
changes made, devices and drivers detected, files added or deleted, communication with the modem,
network settings, and so on.

At startup, the system log records how the Bytton LTE machine begins operation, so the first messages
are those generated bu the “kernel” operationg system.
Also, the NTP client or other timekeeping ressources are not yet running, so the time stamps are always

Afterwards, the other application begiin to run on the equipment.
Correspondingly, in the log you will see records of the kernel or of the user, debug messages, info or
warnings:
