[Beowulf] [External] RIP CentOS 8 [EXT]

Wed Dec 9 22:44:53 UTC 2020

Rolling is not ideal when you have to compile software against the
installed libraries or kernels. If you have or are running Arch Linux you
will know what I'm talking about. There are regular niggles with things,
especially with compiling your own software that needs recompiles pretty
regularly.

It is very strange they have gone from stable controlled releases to
basically the complete opposite. I'm actually grateful though to have such
a strong reason to move on, as we have had quite a number of issues with
Redhat support where bugs can't/won't be patched. Also if we move to Ubuntu
or Debian we will be much closer to the development environments for most
of our researchers.

Cheers,

Lance
