Nah, that sounds just like short for "I sometimes wear the devops hat" - that is, the author probably has to switch computers regularly. Productivity as a devops/sysadmin has different requirements than regular developer productivity. In the former case, you'd prefer standard terminal apps and default settings. In the latter, you'd customize the hell out of your CLI and editing experience.

Yes that's also key for network admins - ironically I found when doing my CCNA that my experience years ago on PDP's cli came in handy on ios (the Cisco os).

[TeMPOraL]

Yes. I wonder though, with proliferation of tools for automating server management, how much does this approach still matter?

[C1sc0cat]

Serious sysadmins /network admins only config kit via out of band terminal mode - that's what the AUX and Console ports are for on Cisco kit

Eh, that doesn't scale beyond a few devices. There's out-of-band management, yes, but often it's in the form of an isolated management network, which allows automation quite conveniently. Even the serial console is often accessible over a network using terminal servers. You usually also want to be able to download and archive your device configuration automatically using eg. oxidized.

That said, being able to work with standard tools is extremely relevant for debugging problems, still.
