I'm not a CentOS admin, but I know a lot of CentOS admins. The concept of Linux distro problems is kind of foreign to me: I'm a Debian guy, the most problems we've had in the past 5 years has been pretty much just systemd (which I file away as "systemd sucks" isuses, not Debian issues).

Basically, everything they've said boils down to package deps are broken and theres no easy way to fix it, and random segfaults and kernel panics (which I have no idea why any distro would ever have this issue).
