What I mean that too many factors are affecting the enumeration,
so that you can not rely on it :
- kernel changes
- driver changes ( partly overlaps with the previous poit )
- hardware changes
- something else ?
There is no policy for this enumeration ( AFAIK ) , so there is
nothing to rely on , except luck :-)
