In fact I wonder if all failure paths should return the 14 version.
What you could do is make this return `std::optional<int>` and have it return
nullopt on failure. Then have the caller do the default part, that way you only
have one place to call the logging method.
```
// If we cannot find it, assume FreeBSD 14.
static const int osreldate = 1400084;
auto osreldate_or_null = GetOsreldate();
if (osreldate_or_null)
osreldate = *osreldate_or_null;
else
log("cannot find osreldate, assuming freebsd 14 (1400084)");
```
