Subjectvfork(2) behavior not consistent with fork(2) (was: vfork(2) fails after unshare(CLONE_NEWTIME) (was: [Bug 215769] man 2 vfork() does not document corner case when PID == 1))
From
> $ sudo ./vfork_newpid
> vfork_newpid: PID: 8479
> vfork_newpid: PID 8479 exiting after execve(2): Success
> print_pid: PID 1 exiting.


I definitely think this is a kernel (or glibc) bug.
execve(2) is supposed to _never_ return 0 (and errno 0).
I submitted a new bug to discuss it.

Please see <https://bugzilla.kernel.org/show_bug.cgi?id=215813>
