[elbe-devel] [PATCH 7/9] elbepack: filesystem: change file permissions during open()

[Thomas Weißschuh]

_write_file() only changes the file permissions after having written all
the data.
Switch to open(opener=) to do this directly when opening the file.

Now _write_file() is unused and can be removed.
