I have the following:
- Bunch of guest VM's that are running Centos 6.3
- Host running Centos 6.3.
- Recently I created a new Centos 6.3 VM to test out something
yum updateafter a fresh install of a minimal server
- Noticed Centos is now at 6.4
I would like to keep the version unchanged as I understand that untested changes have the ability to introduce instability (I'm learning server admin/Centos so that I can develop my own applications that automate various 'needs', one such need is to download data, another is to perform analysis on the downloaded data, and yet another need is to execute certain actions based on the analysis).
I'm in the
Dev phase of
Dev -> Test -> Prod with respect to implementing what I'm doing, so up-time and stability isn't "necessary" at this stage, however, I would like to ensure I've done all I can to ensure up-time/stability will be solid when time does come to have a
Prod environment. So, I would like to keep my guest and host KM's running 6.3 until I decide that an upgrade is necessary and/or provides significant benefit(s).
A few questions:
- How do I prevent automatic upgrades from occurring to versions of the server OS when performing
- Is there a "standard" location on the internet for finding what changes occur in a version upgrade?
- Am I being paranoid about server version changes with respect to stability?
