Right. But it's a big company and I can't influence when or how ESX gets
upgraded.
I can only prepare my VMs for their new lives in this hard, cold, virtual
world; and this
was the first attempt with Debian 9.2 on the current VMware release.
Results were bad.

If I am doing my job OK, that VM will never once be booted in its
years-long lifetime. But
if  the boss ever sees that "TCP performance may be compromised" message on
a
production server, or if it ever kills or cripples the OS or apps, I will
have a very personal
problem very rapidly.

It's really more about sociology than about computer science.
