Fedora Core 4 and 6

[JCR]

Hello,

VPS comes with Fedora Core 4 but I saw that the latest version was Fedora Core 6; is there any reason to saty with Core 4? Should we update to 6?
Thanks

Plesk 8.0 doesn't currently support Fedora Core 6 - see the swsoft list of supported OSs (http://www.swsoft.com/en/products/plesk8/reqs/)

Remember each Virtuozzo Virtual Environment (VE) (http://www.swsoft.com/en/products/virtuozzo/) aka VPS isn't a real server, its an image that makes calls on the host operating system. You've got no 'real' control of the hardware, its all an illusion.

The VEs are built from images of the host OS, and the VE is managed via a combined Virtuozzo/Plesk control panel. Plesk would need to be updated before the OS could be upgraded, and that might break some customer's existing installations.

Everything we do with VPS is in userspace. Because the kernel API remains mostly constant there are very few applications that need the later kernel (2.6.18).

The idea of high-availability production servers is that once they are installed and configured you leave them alone. Having the latest version is not always A Good Thing - keeping it stable and reliable is far more important.

Your userspace applications can be updated as much as you want, and if it goes wrong, well you did create a backup didn't you?

Play with the latest kernels on a private PC that isn't used for production purposes, not one that hosts several tens or hundreds of other independent Customers.

Teej,
Thank you for the answer. I understand better now why we have Fedora Core 4 and why it is ok that way.
