Changing user while being root will leave you to the root homedir.

In a new debian 9.8 installation i noticed that:

root@s165:~# pwd
/root

root@s165:~# su chomwitt
chomwitt@s165:/root$

..and from there i cant even execute ls.

$ man ls
man: can't change directory to '/root': Permission denied
man: command exited with status 255: sed -e '/^[[:space:]]*$/{ N; 
/^[[:space:]]*\n[[:space:]]*$/D; }' | (cd /root && LESS=-ix8RmPm Manual 
page ls(1) ?ltline %lt?L/%L.:byte %bB?s/%s..?e (END):?pB %pB\%.. (press 
h for help or q to quit)$PM Manual page ls(1) ?ltline %lt?L/%L.:byte 
%bB?s/%s..?e (END):?pB %pB\%.. (press h for help or q to quit)$ 
MAN_PN=ls(1) pager)


In another 9.6 , changing user will put me in the user's home dir.
