Hello,
How can I be sure which Oracle Linux release I'm running, other then by "cat /etc/oracle-release"?
I've got a third party company installing the OS on a server, and it supposed to be Oracle Linux 7.5.
After the installation was done, we noticed that it was on Oracle Linux 7.7 though.
We asked them to review it, and they claimed that they've changed the kernel back to distribution 7.5.
According to the following outputs, can we really be running Oracle-Linux 7.5?
# awk -F\' /^menuentry/{print\$2} /etc/grub2.cfg

Oracle Linux Server release 7.5
The problem is: in the 'history', there's a line with: "vi /etc/oracle-release". So my concern is that the release was "forced back" to 7.5 by manually modifying file /etc/oracle-release.
So, again, how can I be sure which Oracle Linux release I'm running, other then by "cat /etc/oracle-release" (since it MIGHT've been modified)?
