I am confused by the fact that even though I installed RHEL 5.1 from DVD (RedHat/5.1.x86_64), when I issue command:
cat /etc/redhat-release
I got:
Red Hat Enterprise Linux Server release 5.5 (Tikanga)
What does it mean? is that to be a release version or kernel version? Is there any other way to confirm that real version of RHEL?
I have this doubt because there will be certain applications that would depend on this.
Many thanks in advance.
