Thanks for the education, Ryan. I checked my Ubuntu 9.04 virtual install where I first saw this problem, and the contents of /etc/sudoers are as described here: https://help.ubuntu.com/community/Sudoers#The%20Default%20Ubuntu%20Sudoers%20File Sure enough, $HOME isn't altered by sudo: ~$ sudo python -c 'import os;print os.environ["HOME"]' /home/philip I observe the same under OS X, so this configuration of /etc/sudoers might not be ideal, but it's popular.
