I am using a kvm ubuntu 10.04 virtual machine to test some features of a kernel module. I grep through the
/var/log files to observe the kernel messages about that module.
To start from a clean state, I remove log files containing older messages by executing
rm -rf /var/log/* and then rebooting the virtual machine. However, after I reboot, the new log files still contain those old log messages. It takes about 5-6 cycles of deleting files and rebooting virtual machine to finally get rid of those log file messages.
Why is this happening? Is there an easier way to cleanup log files?
