I have been involved in "Enterprise Linux" (RHEL, CentOS, Fedora, Oracle Linux, etc.) server, network, and systems administrator since 2005. Of course I've "dabbled" heavily in the other less "elegent" flavors like SunOS, Solaris, Debian, Ubuntu, Kali, Pidora, and Raspbian over the years. There's far too many Linux flavors to pretend that I've tried them all, but I've played with a LOT of them, and on a LOT of different hardware, with MANY different configurations.
