FWIW, for scalability I'd probably use $(sys.uqhost) to ensure that classmatch
is not matching against another class that may exist and just happens to look
like a valid hostname.
classes:
"svxx" expression => regcmp("sv[0-9]{2}", "$(sys.uqhost)");

Subject: Re: Matching host names by regexp
Perfect, why didn't I think of that - nice and simple. With this and a
more precise (and less readable) regexp, I now have the following:
classes:
"svxx" expression => classmatch("sv[0-9]{2}"); #sv00, sv01, ..., sv99
Thanks,
Erlend
