Hello,

I get about 50 of these denied-type errors on reboot after installing
Core 2.  What might be the problem(s)?

These messages are caused by SELinux needing to do things to set permissions and context right for it to work as designed. If you want to run selinux, there is a list that will help you with setting things up to work, as designed.

Otherwise, you might want to add to your /etc/grub.conf file the below:

kernel /vmlinuz-2.6.6-1.406 ro root=LABEL=/ selinux=0

The selinux=0 is what you want to add to the kernel line. I just added my boot line so you know what line that I was referring to.

Also there is a way to set the selinux to off in some config file. I am not sure what it is. You might need to search the archives for how to disable SELinux.

I did notice two programs on my search for selinux on my computer. I have not tried to run them. They are listed below. /usr/bin/selinuxdisable /usr/bin/selinuxenabled

I imagine that one disables selinux, which you might desire. The other should enable selinux.

I hope running them dos not cause any problems.
