Hi, 

I've just started using EPICS 3.14.6 and encountered the same problem as
Benjamin Franksen from Bessy (original tech-talk posting follows this
email).

At Diamond we use the same approach i.e. produce an expanded db file
using a substitution file and an (externally defined) template file. In
R3.13.x we used to do this by having the following lines in the
Makefile.Host file of the /Db directory:-

DB +=  test.db
USES_TEMPLATE += $(TEMPLATE_PATH)/test.template

This didn't seem to work in EPICS 3.14.6, due to an error in the
RULES.Db file. The following corrects this problem:-

--- RULES_Db.ori        2005-06-08 17:02:07.000000000 +0100
+++ RULES.Db    2005-06-08 17:02:37.000000000 +0100
