Yes, I agree. I think the current O_APPEND behaviour indeed does not make much sense, and O_EXIST would make more sense and actually be in line with what the documentation suggests. I have thus prepared a PR that fixes this and makes it work like you want: https://github.com/systemd/systemd/pull/7983 It's a change of behaviour, but i think one we can get away with as the old behaviour really didn#t make much sense and didnt match what the documentation suggested. > Also, how do I use a specifier in an argument here?

And then my answer is: use "f", as you originally wanted to.
