I just read Insider #12 and the related article.
It is my opinion, with all due respect, that the CentOS issue must be taken with a different approach.
XCP-NG is relaying on the fact that it will be supported until 2024 and this means time to decide and take action. Not so sure.
CentOS is already falling behind other distros such as Debian and so is XCP-NG compared to other Debian based products.
More so, the community is already feeling this situation. New hardware is coming out in which XCP does not run out of the box. I just had an issue with a new Intel 10 based machine in which in spite of hours of dedication I had to give up and switch to a different product.
Just the Idea of CentOS dying will keep new users coming on the XCP boat so a clear future has to be decided soon and action taken.
