What is it?:
If the user is in sudo or admin group and
$HOME/.sudo_as_admin_successful does not exist, we show a message to
read `man sudo_root`
https://git.launchpad.net/ubuntu/+source/bash/tree/debian/etc.bash.bashrc#n84
Sudo program creates this file on first successful sudo run on Ubuntu.
History:
I was able to trace it back to 2006
https://git.launchpad.net/ubuntu/+source/bash/tree/debian/changelog#n2375
My guess is `sudo hint` change was introduced to help users get
acquainted with sudo (after some confusion and complaints on
ubuntuforums).
The history of this page goes back to 2005:
https://help.ubuntu.com/community/RootSudo
I found a reference to sudo patch:
https://git.launchpad.net/ubuntu/+source/sudo/tree/debian/changelog#n2309
==================
debian/patches/ubuntu-sudo-as-admin-successful.patch: adjust sudo.c so
that if the user successfully authenticated and he is in the 'admin'
group, then create a stamp ~/.sudo_as_admin_successful. Our default bash
profile checks for this and displays a short intro about sudo if the flag
is not present
==================
At some point, this was merged upstream
https://github.com/sudo-project/sudo/commit/6d0395ee687f64144983446d140a68b45d2c557d
in 2021, it was made configurable upstream
https://github.com/sudo-project/sudo/issues/56
Why are we discussing it now?:
sudo-rs does not create this file.
https://bugs.launchpad.net/ubuntu/+source/rust-sudo-rs/+bug/2120249
Proposal:
I think this change has served us well and users are familiar with
sudo now. A sudo user is created by default not just on Ubuntu but on
a variety of distributions.
1. We should drop the sudo hint block in /etc/bash.bashrc.
2. Create a page (sudo) on Ubuntu Server docs
https://documentation.ubuntu.com/server/ and move some content there.
(I was going to create a page for sudo-rs as sudo providor anyways)
The alternate is we introduce this feature to sudo-rs and carry the delta.
Please let me know if you have any concerns. I am planning to raise an
MP next week.

Ravi
