 Fake file descriptor (FD) is used in regular mode in libpil4dfs.so for efficiency. open() returns fake fd to applications. In cases of some APIs are not intercepted, applications could crash with the error "Bad File Descriptor". Compatible mode is provided to work around such situations.
 Setting env "D_IL_COMPATIBLE=1" turns on compatible mode. Kernel fd allocated by dfuse instead of fake fd will be returned to applications. This mode provides better compatibility with degraded performance in open, openat, and opendir, etc. Please start dfuse with "--disable-caching" to disable caching before using compatible mode.
 
-### Child Process Inheritance
-
-Normally child processes inherit environmental variables from parent processes. In rare cases, e.g.
-scons, envs are striped off when calling execve().  It might be useful to force pil4dfs related env
-set in child processes by setting env "D_IL_ENFORCE_EXEC_ENV=1". This flag is 0 if not set.

 ### Directory caching
 
 To improve performance, directories are cached in a hash table.  The size of this hash table could
