My intention wasn't to make it opaque, ENVSYS_GSTRING uses the
genstr member in envsys_data_t that is defined as:

char genstr[ENVSYS_DESCLEN]

so it's an array of 32 chars. But it's generic in the sense that you
can add the string that you want on it, perhaps the name is not the
best one... but I was out of ideas.

My first idea was to use a static table like ENVSYS_DRIVE uses, but
IMHO the way I choose gives more flexibility. It would be useful in
more drivers in the future, don't you agree?
