파일 권한이 허용된 작업과 일치하지 않습니다...?

CentOS 9 VM의 파일 권한과 관련된 몇 가지 문제가 발생했습니다. 저는 이전에 이렇게 많은 문제를 겪어본 적이 없으며 설치 중에 선택한 보안 옵션 및 파일 시스템(GUI STIG 및 ext4)과 관련이 있는지 궁금합니다.

예시 질문 1:

동일한 디렉터리에 있는 두 개의 Python 파일인 ls와 stat는 동일한 권한을 표시합니다.

$ls -al config.py run_app.py
-rwx------. 1 myuser myuser 20K Aug  4 19:33 config.py
-rwx------. 1 myuser myuser 50K Jul  8 10:51 run_app.py

$stat config.py run_app.py
  File: config.py
  Size: 19873           Blocks: 40         IO Block: 4096   regular file
Device: fd05h/64773d    Inode: 1971283     Links: 1
Access: (0700/-rwx------)  Uid: ( 1000/myuser)   Gid: ( 1000/myuser)
Context: unconfined_u:object_r:user_home_t:s0
  File: run_app.py
  Size: 51016           Blocks: 104        IO Block: 4096   regular file
Device: fd05h/64773d    Inode: 1969096     Links: 1
Access: (0700/-rwx------)  Uid: ( 1000/myuser)   Gid: ( 1000/myuser)
Context: unconfined_u:object_r:user_home_t:s0

그러나 lsattr은 제대로 작동하지 않습니다.

$lsattr config.py run_app.py
--------------e------- config.py
lsattr: Operation not permitted While reading flags on run_app.py
$sudo lsattr run_app.py
--------------e------- run_app.py

run_app.py를 cat/편집/실행할 수도 없습니다. 이 세 가지 작업은 config.py에서 제대로 작동하지만. run_app.py를 사용하는 모든 작업에는 Sudo/root가 필요합니다.

질문 2 예시:

Python 패키지를 가상 환경에는 설치할 수 없지만 로컬 사용자 환경에는 설치할 수 있습니다.
