Starting with Debian 10 buster the way how the su command is used has been changed. By default execution of the su command no longer provides you with expected user environmental variables.

In the case of a simple switch to administrative user root by executing su with no arguments the expected root's PATH variable is no set properly.

Symptoms

Here is an example:
$ su
Password:
# reboot
bash: reboot: command not found                                                                        
# adduser                                                            
bash: adduser: command not found
bash: reboot: command not found  - Debian GNU/Linux missing path to /sbin/ directory
bash: reboot: command not found - Debian GNU/Linux missing path to /sbin/ directory

Solution

The trick on how to fix this inconvenience is to explicitly tell the su to set environment variable as if the user logs in directly. This is can be done by the use of - switch.
