You can tell Augeas to copy if it can't do the (much safer) write to
temp file + rename by setting /augeas/save/copy_if_rename_fails to some
arbitrary value.

IIRC, on Debian it points somewhere else, so we'd need some variation
between RH and Debian. But if there's something that works for either,
and avoids the cross-device symlink I'd like to change the stock lens.
