I just did that zcat step - once each for a different reboot and named the files uniquely. A diff command shows -

I found this in the config-4.4.155.68.txt and /boot/config-4.4.155-68-default. Module compression is not set but the modules in /lib/modules/… are. Getting confused.
CONFIG_MODULE_SRCVERSION_ALL=y
# CONFIG_MODULE_SIG is not set
# CONFIG_MODULE_COMPRESS is not set
CONFIG_MODULES_TREE_LOOKUP=y
OBS??? Can you direct me please to where to start?
Thanks,
Chris.
