I don't have access to the GHC source just at the moment, but presumably that
is an interface to creat() instead of open(). creat() is documented as:
creat() is equivalent to open() with flags equal
There could be reasons that you would want to pass, say, O_CREAT|O_RDWR|
O_APPEND and omit O_TRUNC.
There are also reasons that you might want to pass, say, O_WRONLY|O_APPEND
with no O_CREAT. The fact that openFile implies O_CREAT sometimes is a
serious misfeature IMHO. That means bug.
