Actually I don't see why we should use sync()/fsync() at all? As you mentioned i a call, modern file […]

I'm fine with whatever means not adding a new thread to libosmocore just for this specific case used seldomly.

One can also use the vty cmd to write the config file to another file, and then over ssh copy over the new file to the old file in whatever sync/safe manner they want.
