The last bit is still true - we only support a single uncompressed
segment followed by a single compressed segment.  I don't know how to
support multiple compressed segments, as in general we can't find out
how long each segment is.  (But I think dracut does it, so maybe we
could copy from them.)

So I've applied this change:
