The filename is a misnomer. ConnMan uses this file for storing the
state. That means ConnMan is reading it at startup and during runtime
it will be writing when the state changes (e.g. a technology is
enabled). This file is under control by ConnMan.
This means you can only modify this file when ConnMan is not running.
If I understood you correctly, you want to have a default
configuration at deployment time, correct?
Correct.
One way how we could fix this, is by introducing a default settings
file which is used whenever the /var/lib/connman/settings file doesn't
exist. I suppose such a file would be located under
/etc/connman/settings. If /etc/connman/settings doesn't exist the
built in defaults would be used.
That works, even the symlink was untouched.
Thank you very much Daniel,
