Grant User Account Ability to "sudo" on OLPC XO

OLPC XO and its Sugar interface is based on Linux, which means managing it remotely should be a piece of cake. Being my daughter's computer, it's neck breaking for me to manage it while sitting at her kiddie table.

So, I sat up an account for myself on her OLPC and was able to remote login into it quite easily. But running "sudo" caused the following failure:

Traceback (most recent call last):
  File "/usr/bin/sudo", line 119, in 
    if __name__ == '__main__': main()
  File "/usr/bin/sudo", line 117, in main
    os.execvpe('/bin/su', cmd, nenv)
  File "/usr/lib/python2.5/os.py", line 363, in execvpe
    _execvpe(file, args, env)
  File "/usr/lib/python2.5/os.py", line 380, in _execvpe
    func(file, *argrest)
OSError: [Errno 13] Permission denied

The Sugar environment had no /etc/sudoers files. And based on what I read online, I found that creating such a file has no effect. I found the only way to gain "sudo" access is to add my user account to the "wheel" group with the following command at the OLPC Terminal:

  sudo usermod -g users -G wheel name

This problem is caused by moving my user account onto the SD Card. The SD Card was formatted to FAT, which doesn't support the UNIX permissions. Once the card is formatted to EXT3 as described in the "Expanding the Storage Space on the OLPC XO" thread, the problem went away.

For clarification, my user account is set-up on "/home/me". Then I moved the user account to the SD Card ("/media/SugarDrive/home/me"). Next, I created a symbolic link from "/home/me" to "/media/SugarDrive/home/me".
