[systemd-devel] [PATCH] install: create_symlink() check unlink() return value

create_symlink() do not check the return value of unlink(), this may confuse the user. Before the unlink() call we check the 'force' argument. If it is not set we fail with -EEXIST, otherwise we unlink() the file, therefore the next symlink() should not fail with -EEXIST (do not count races...).
