yes, this works perfectly.  a very powerful technique for reducing zone 
admin chores when zones contain the same records.  If you have more than 
one group of zones, then use file common1 for group1, common2 for group2, ...

note that is only works on the zone master.  the zone slave will need a 
unique name per zone backup file.

To obtain the same type of leverage within non-identical zone files but 
share some records, use the control statement $INCLUDE.   common 
NS,  common MX, and $TTL are the types of records amenable to $INCLUDE 
treatment.
