A mysterious file keeps appearing on my startup disk. It's most likely a typo in a script or something, but even though it's being created with my user account as the owner, that hasn't helped me narrow it down.
Would it be safe for me to lock my system's startup disk to prevent writing to the root folder? As far as I know nothing needs to be written there, as all the various directories used by the system are already present such as
/System and so on. But even so, I'm wondering if this is safe to do, or will it ruin my system?
I'm hoping that by locking the volume I can force whatever is creating the file to report an error in a log file, and also to prevent similar clutter in future (some badly written programs have a nasty tendency to put log files there), but obviously it's no good if it'll break something!
