Here's the script I used to verify, it should create the file
/etc/rootfiletest. By using the partial trick or creating parse
errors, this is easy to turn into a root shell.

Note: I'm a c programmer, I don't know python at all, it's probably
the worlds worst python code - I used python because I was reading the
python3-lxc code.

taviso@...ntu:~/tmp$ ls -l /etc/rootfiletest
ls: cannot access /etc/rootfiletest: No such file or directory
taviso@...ntu:~/tmp$ rm -rf /tmp/?0* /tmp/exploit/
taviso@...ntu:~/tmp$ python3
taviso@...ntu:~/tmp$ ls -l /etc/rootfiletest
-rw-rw---- 1 root root 0 Apr 15 12:53 /etc/rootfiletest
