I'm not sure, but check out umask

Sorry I was looking at this:
cp: overwrite `/inst/cdrom', overriding mode 0777? y

I set my selinux to permissive, it was successful

In case of any SELinux errors please first look at /var/log/audit/audit.log (or /var/log/messages if the auditd service is not running) for clues.
