thats good to know at least.


> further to that are there plans aside from CentOS to move the rpm base to say Alma or CoreOS or Silverblue even. (both are ostree based) as Ive seen the debian build deploying with ostree onboard? or is the plan to drop rpm based distros long term and just run with debian ?

Welp, that kills our use case for upgrading, first we need
openstack-helm in the mix, second it sounds like it will be a
fork-life upgrade, not backwards compatible seeing as the os changed
from CentOS to Debian
Im familiar with yocto, so at least bring ostree into the mix is a good idea.

LOL Wind River should just hire me to work on STX full-time. I can say
im not 100% happy about the dropping of CentOS, in lieu of an Os
change to CoreOs, or other, Yocto/Debian is nice
but... thats a reinstall for sure. a good amount of interruption to
prod environments and capex for new servers.
