hello jkline,
(additional note, since this is marked as a “solution”, this advice is provided as a temporary workaround. this unintended bug will be addressed in a near-future release. apologies for any inconvenience caused.)
thanks for all your debugging efforts here, very much appreciated!
until i can look into this issue more deeply and get a fix issued to address this, it is possible to avoid the file from being rewritten on a reboot. namely, once you’ve made your by-hand edits, make the file immutable. in this manner, nothing is able to modify it or its contents until reverted to a mutable state.
to achieve this, log into the Shake, edit the file according to your desires, and then carry out the following command on the command line:
> chattr +i /opt/settings/dataC/heli_ewII.d
cheers, hope this helps. and thanks again!
richard
