os.execl fails to execute Python

[alexyao2015]

From a python script, attempting to run os.execl with Python as the executable fails because Python seems to locate /install as its path instead of the real path. This installation was installed using uv, but I'm still experiencing this issue.

In the real world, this affects the yocto poky project which works fine with other Python distributions but fails to run with this one.

Example:

import sys
import os

os.execl(sys.executable, "test")

Output:

$ python test.py
Could not find platform independent libraries <prefix>
Could not find platform dependent libraries <exec_prefix>
Python path configuration:
  PYTHONHOME = (not set)
  PYTHONPATH = (not set)
  program name = 'test'

  environment = 1

  safe_path = 0
  import site = 1
  is in build tree = 0
  stdlib dir = '/install/lib/python3.11'
  sys._base_executable = '/usr/bin/test'
  sys.base_prefix = '/install'
  sys.base_exec_prefix = '/install'
  sys.platlibdir = 'lib'
  sys.executable = '/usr/bin/test'
  sys.prefix = '/install'
  sys.exec_prefix = '/install'
  sys.path = [
    '/install/lib/python311.zip',
    '/install/lib/python3.11',
    '/install/lib/python3.11/lib-dynload',
  ]

Using another python distribution (e.g. from Ubuntu or PyEnv) that has the correct compiled in paths:

$ python test.py
