@Zanna I've been away from the site for a few days except for short(ish) bursts of reviewing, but I think it's time I finish writing that Q&A. Do you want to see the most recent draft? I do not like it very much and I might throw out most of the changes since you last saw it, so I'd be interested in your input.

It would be easier for you to give input if I kept working on the section I might totally throw out. But since I might totally throw that section out... :)

sure, yes! I may be afk on and off

Same here. I was going to say, "now I will finish" but I realized that might be wrong and said, "I think it's time I finish" instead. :)

For years, Ubuntu has [shipped a patched version of `sudo` that preserves `$HOME` by default][1]. Besides Ubuntu and its derivatives, [very few other operating systems (perhaps no others) do this][2].

In terms of *what* the change is and how it affects users, the key points are:

- **As of Ubuntu 19.10, <code>sudo *command*</code> does what <code>sudo -H *command*</code> does in previous releases.** It can…

I don't know how valuable the detailed rundown of the history is.

it looks great!

the most important stuff is at the beginning

if I just want to know what it's all about, I only have to read the first paragraph

It may get long.

if I'm curious about the story, I can read on

Btw thanks for reading it!

@EliahKagan that's not a problem

The post may get long, is one of my concerns. Sorry, I already said that.

@EliahKagan sorry it took so long

@Zanna That was... a quite short time.

I was afk for almost all of that time.

And shall be again now! (bb soon)

:)

haha :)
