Comment (by bonefish):
Implementation hint:
- Add a parameter for the umask to `_kern_exec()` and pass the current
umask [https://dev.haiku-
os.org/browser/haiku/trunk/src/system/libroot/posix/unistd/exec.cpp?rev=33670#L106
where invoked].
- In [https://dev.haiku-
os.org/browser/haiku/trunk/src/system/kernel/team.cpp team.cpp] pass the
umask on (`_user_exec()` -> `team_exec()`) and add it to the `team_arg`
structure (defined in same file).
- In [https://dev.haiku-
os.org/browser/haiku/trunk/headers/private/system/user_runtime.h?rev=33670#L22
user_runtime.h] add a umask field to the `user_space_program_args`
structure and set it in [https://dev.haiku-
os.org/browser/haiku/trunk/src/system/kernel/team.cpp?rev=39864#L1084
team_create_thread_start()] (from the `team_arg` field).
- In libroot's [https://dev.haiku-
os.org/browser/haiku/trunk/src/system/libroot/libroot_init.c?rev=36323#L38
initialize_before()] set the umask from the newly introduced
`__gRuntimeLoader->program_args` member.
