/etc/logrotate.d/ntp.new , New method seems a bit skewd too me .

The logic operator in the new logrotate seems very odd to me .
the "!"(Not) operator is outside all logic interpretation levels thus makeing the logic of the line upto "||" as NOT if it is executable , even if it isn't due to the "||" . Sounds like Double negative to my way of thining .

Can someone run me thru the logic of this ?
