On my home system I received error when running unit tests like:

Message DHCP4_SERVERID_LOADED server-id /home/reed/opt/bind10/var/b10-dhcp4-serverid has been loaded from file %2
assertion ""Excess logger placeholders still exist in message" == NULL" failed: file "../../../../src/lib/log/log_formatter.cc", line 69, function "void isc::log::checkExcessPlaceholders(std::string*, unsigned int)"

I am using --enable-logger-checks. The build farm also uses that.
I am not sure why this was not seen  on the build farm.

I added the missing value for dhcp4 and dhcp6 and the make check completed.

It had slight review on jabber.
