Linux has always been blessed. As we have a large number of people working for the betterment of the product, we’ll have bug fixes/security updates every now and then. This has got 2 sides.
- The good part- if you keep on upgrading; you will have a more secure, bug-free product.
- The bad part- if you never upgrade; the whole world knows the security vulnerabilities of the outdated version. I guess this could be as good as tweeting your root password.
So, we’ve got to update the systems as and when the updates arrive. But, an update once in a month will mean a reboot once a month, which will mean monthly server downtime. This is where Ksplice comes into the picture.
