So as a late linux adopter, in Debian, I am wondering why people see value in SUSE and RedHat since all my experience has been the SLA value is .. dreck. No problem we had with a RH kernel or OS behaviour was fixed inside our $SLA$ in the EL release we had. All problems were either WONTFIX or re-install later EL.
Debian update/upgrade appears to work. Fixes get applied. What am I missing? If they want to own SAP-ON-LINUX or ORACLE-ON-LINUX why should I worry?
I am more concerned about GPL and ZFS these days, than commercial backing: I dont think it actually adds value to me. (20+ nodes in a research cluster, cloud)
