Exactly.  I'm no expert on either the GNU autoconf variables or the FHS
definitions.  The point of principle I was heading towards was that to
avoid discussing:
   "Samba's feature 'X' should be FHS directory '/Z'"
and rather discuss:
   "Samba's feature 'X' should map to autoconf '$Y'".

Hopefully (though I'm no expert), autoconf's '$Y' is reasonably close to
FHS '/Z', but in case of divergence (which might lead GNU sites to prefer
one set of defaults and FHS sites to prefer another) I then added:

Perhaps the full form of an "--enable-compliance" feature would be:

defaulting to "gnu", having "fhs" as an acceptable alternative and perhaps
issuing a deprecation/expiry-notice warning on "backward-compatibility".
(A site can choose its preferred compliance model then use "--exec-prefix"
etc. for fine-tuning...)

Good summary.  That's exactly the sort of principle my long-windedness was
meanderingly bumbling towards.  Concentrating discussion on location
*types* rather than exact values.
