(Take a look at the Perl script /usr/share/logwatch/scripts/shared/onlyservice . It's just matching on one of several different Perl regular expressions that include the string `init'.) I see that the Perl regular expressions are suboptimal in that the quantifier `*' seems to be used in several places where it should be `+'. This consumes more CPU than necessary. > And why?
