It's actually sort of shocking just how much some of candidates I've interviewed for sysadmin jobs don't know about how computers actually work, but it's not exactly a new problem nor is it restricted to "young bucks". One of the stereotypes I encounter over and over again is what I call the "Solaris Guy". (On the basis of that being by far the most common OS the person has the most experience with.) Said guys have been in the industry for 20 years as "Unix Admins" but somehow for that entire time they've coasted along in low-level positions where all they do is install packages, restart daemons, and run scripts written by someone else. And they apparently lack the will or interest to explore any deeper than that. They can spout off the syntax for various commands from memory with spooky accuracy (far better than my swiss cheese brain can manage), but if you probe them on what the command actually *does* or how you'd go about troubleshooting it if it fails... zilch. Plenty of dictionary knowledge, ZERO conceptual grasp.The young bucks they have in there now don't know what to do if the package manager doesn't have it. Get off my lawn!
(Also note "Solaris Guy" isn't just into UNIX, there are "Solaris Guys" all over the tech landscape.)
Anyway. Isn't the best customization you can do to sendmail uninstalling it and using Postfix instead? :lol:
