To simplify maintenance and reduce errors for all the installations where we want to take the per-environment defaults, I want a way for users to just define SYS in one place, preferably a macro in dbLoadRecords. That would let you cut and paste one st.cmd line into new systems, while maintaining per-environment defaults centrally. Does anyone have a way to do that, or good alternatives for this type of problem?

Another solution I occasionally use is "database overwrite"

dbLoadRecords(my_default_database.db, recordPrefix=FOO)
dbLoadRecords(overwrite_default_database.db, recordPrefix=FOO, fieldValue=TOTO)
iocInit

The second db file overwrites (or *complement/complete) the configuration in the first db file.
Beware records types and names need to be the same, so this method is more appropriate to change the values of fields
