The company wants something that is more up-to-date, with newer packages, a new kernel, and free, rhel flavored for development purposes.
After reading: https://www.vertica.com/docs/12.0.x/HTML/Content/Authoring/SupportedPlatforms/MCandServer.htm?zoom_highlight=rhel
It seems like all operating systems except RHEL are quite old, reached their End of Standard Support/EOL, or are near End of Standard Support/EOL:
RHEL:
Amazon Linux 2 -> 30.06.2023 (EOL)
RHEL 7 / Centos 7 / Oracle Linux 7 -> quite old, only maintenance (Standard Support already reached, 2 years ago: 2020-08-06, only maintenance updates until: 2024-06-30)
openSUSE Leap 42.3 -> Jul 1st 2019 (Reached EOL)
Even deb family looks quite bad:
Debian 10.x -> 08.2022
Ubuntu 18.x -> 04.2023 (eol is 2028)
Will you support Rocky Linux or Alma Linux? It looks like overall you probably won't support any os that is free from RHEL family.
