Oh, wow. :-)
There was a similar bug report for "sudo" the other week where the
conclusion was "well, just use -i" (because then $HOME would be set
correctly). Does this mean that su and sudo behaves differently in
Emacs in this area? Let's see...
sudo -i:
root@sandy:~# echo $HOME
/root
(user-real-login-name)
"root"
sudo bash:
root@sandy:~# echo $HOME
/home/larsi
(user-real-login-name)
"root"
[larsi@stories ~]$ su
Password:
root@stories:/home/larsi# echo $HOME
/root
(user-real-login-name)
"root"
Uhm...
So when I su on this machine, I'm not getting /home/larsi/.emacs?
This is kinda confusing.
