I am trying to rename default user 'pi' to something else, and I am failing miserably.
Raspbian is based on Debian, so I assumed that it behaves as Debian, am I wrong?
What I tried?
I did normal route, as logging as root and using usermod - it does not work. I keep getting errors that user pi still runs processes of various PIDs. I tried to kill all processes related to the user by using
killall -u pi and it also did not work. I used then
pkill -9 -u pi without a success. After each of these commands, when I run
usermod -l newname pi, the system still reports running processes related to the 'pi' user. Why? What am I doing wrong? Yes, 'pi' is logged out, and I am logged in as a root. I know that I need to change few other things too, but I cannot go even through login change due to ongoing processes I cannot kill.
Edit: After some comments, I realized that my question looks like I ask how to change a username. I rather ask why my attempts to kill processes related to user pi failed. I will do my best to be more precise next time. Thank you all for hints!
