für 2. hab ich mal noch nen neues bugticket aufgemacht:


i`m trying to use vzlogger in foreground and i don´t need httpd. local is disabled, so is daemon. i would expect that vzlogger starts in foreground and does not start httpd - but vzlogger starts as daemon instead and also starts httpd, which is a major issue - as starting a tool which opens a listening port when explicitly being told not to do so imposes a security risk.
