You should be using
https://manpages.debian.org/stretch/login/su.1.en.html
Someone on stackexchange told me that "sudo su" is wrong now.
I don't use 'sudo' normally, but don't understand why one would use su that way .
When just
is all that is needed.
I can't seem to duplicate this on Debian 9, and as far as Debian testing (will be Buster)
who knows, ? Since it has not yet been released as a stable version, who knows what the norm will be ?
The shutting down issue, is another question/topic all together,...maybe show us exactly what command you are using to shut down ?
Edit===HOAS responded while I was typing:
EDIT: please open a separate thread for your shutdown problem.
Agreed, so don't answer me here, give those details in the new topic.
by kanliot ยป No idea if I've lost data. When is Debian going to figure out that udev is just mocking you?
Me neither, I never lose data, but that is because I all ways make a backup , before shutting down, and that way have all the data saved, in case something went wrong.
As far as "When is Debian going to figure out that udev is just mocking you?", hmm, I don't know, my question, When will trolls learn that we have nothing to do with Debian Development, and are just Debian Users as well,... I suppose your system , Debian will figure those things out when the system admin learns how to administer and configure the system properly . I do know I had to do a lot of work to get Debian 9 working properly, for me, but yea, Debian it's self is not going to do that, the system admin needs to do it.
