因此，我們有一個需要apparmor配置文件（客戶端授權）的django應用程序。它運行在位於/opt/fact-virtual-environment的Python虛擬環境中。應用程序本身安裝到/usr/share/fact在apparmor配置文件中加載Django應用程序的設置
以下是我的個人資料，到目前爲止（內置大多是用AA-genprof工具）：

}
...和/usr/bin/fact命令是一個簡單的包裝：
#!/bin/bash
## This script is for running the 'fact' command on staging/prod, it sudos to
## the 'fact' user before executing /opt/fact/bin/fact
## It is installed as '/usr/bin/fact'
PYTHONPATH=/usr/share/fact
PYTHON_BIN=/opt/fact-virtual-environment/bin/python
DJANGO_SETTINGS_MODULE=fact.settings.staging
if [ "$USER" != "fact" ];
then
sudo -u fact $0 $*;
else
PYTHONPATH=${PYTHONPATH} DJANGO_SETTINGS_MODULE=${DJANGO_SETTINGS_MODULE} ${PYTHON_BIN} -m fact.managecommand $*;
fi
我已經啓用了很多讀取權限，我知道我不需要，比如在調試嘗試中設置的整個/usr/local/lib/*。一些令我感到非常震驚的事情是，當我運行service apparmor reload（或重新啓動）時，我的配置文件似乎不會重新加載。我似乎得到不同的結果，如果我重新啓動服務與aa-complain usr.bin.fact其次aa-enforce usr.bin.fact。
現在，當我運行我的命令，並檢查系統日誌，我看到以下內容：
Feb 11 15:08:48 spiffy kernel: [1228245.774660] type=1400 audit(1423620528.359:14142): apparmor="DENIED" operation="open" parent=12884 profile="/usr/bin/fact" name="/usr/local/lib/python2.7/site-packages/" pid=12885 comm="python" requested_mask="r" denied_mask="r" fsuid=111 ouid=0

..和我的Python應用程序barfs：

ImportError: Could not import settings 'fact.settings.staging' (Is it on sys.path? Is there an import error in the settings file?): cannot import name current_app
，設置文件，它在尋找是位於/usr/share/fact/fact/settings/staging.py
我完全不能混淆爲什麼我不能讓這個應用程序運行在其apparmor配置文件。配置文件中的設置應該允許它。這是怎麼回事？
