Well, in theory libsystemd-login.so could export a function for that for
you. However, that's dangerous business, if your services runs under a
different UID than the user. In general it's a huge security issue if
privileged code and unprivileged code write to the same directory (with
the exceoption if they do that with mkstemp(), which doesn't sound right
here...)
