Has squid something to do with this?
I did more research and my guess appears to be right. Squid has cached the files. I installed the squid reporting module 'sarg' and it shows quite some activity during the rebuilding time of chroot. Here are my installation notes to get this working: apt-get update apt-get install sarg nano /etc/sarg/sarg.conf change output_dir to '/etc/debian-edu/www/squid-reports' change date_format to 'e' execute report with 'sarg x' Check report with browser https://www/squid-reports/ Kind regards, Roman
