I'd also like to get rid of 'lastlog' and 'wtmp' but even if the man page claims that they will not be created if they don't exist, they come up again and again; another candidate of not needed log is /var/log/Xorg.n.log ... thx matthias -- Matthias Apitz Manager Technical Support - OCLC GmbH Gruenwalder Weg 28g - 82041 Oberhaching - Germany t +49-89-61308 351 - f +49-89-61308 399 - m +49-170-4527211 e - w http://www.oclc.org/ http://www.UnixArea.de/ b http://gurucubano.blogspot.com/ «...una sola vez, que es cuanto basta si se trata de verdades definitivas.» «...only once, which is enough if it has todo with definite truth.» José Saramago, Historia del Cerca de Lisboa
