Hello There,


Just to supply another point of view, I'm sticking (i.e. the whole
network I manage) to SL7 (and CentOS8 afterward) because RHEL is the
only open source OS that is qualified for big VLSI CAD tools
(Cadence, Mentor, Synopsys). This is my only reason, but it's a
mandatory one...

I take this occasion to send a big thank for the SL team and it's
great jobs all those years.


Best regards,
