Yes, carrying your own environment into rootland can be a bit of a
gotcha. Another thing I find that makes me want to 'sudo su -' is that
sudo only does "real" commands, not bash builtins:
victor@ss07:~$ [1] sudo history
Password:
sudo: history: command not found
Admittedly, there aren't a lot of occasions when you might want to do
that; 'history' is the main one that I'm aware of. I've not found a
way round that yet.
