The problem can be simpler if you're assuming a machine with only
one user, or more complicated if the obvious disk location is
either read-only to the user, or volatile.
You also might want to clear all such flags upon an upgrade. If
so, it's not just a file needed, but a sortable version
string.
Preferred approach is usually to respond to one of the
conventional argv switches. And let the user decide.
