switch the verbose level without restarting server > very interesting
feature which I would have used yesterday (If i have this command !)
during a support session with a sysadmin of my company !

May be as for named (named-checkzone, named-checkconf) or apache 2
(a2ensite, a2dissite, a2enmod, a2dismod), a command by functionnality
may be more readable : syslogng-trace / syslogng-stats etc.
