For example, using this command:
dpkg-query -W -f '${Package} - ${Source}\n' | grep bind9
I get the following output on my machine:
bind9-host - bind9
bind9utils - bind9
dnsutils - bind9
libbind9-90 - bind9
libdns100 - bind9
libisc95 - bind9
libisccc90 - bind9
libisccfg90 - bind9
liblwres90 - bind9
does this mean all of these packages are compiled from a single bind9
source package? could anybody explain more inner working here?
