8commonio.c: fix unexpected open failure in chroot environment
9
10When using commands with '-R <newroot>' option in our pseudo environment,
11we would usually get the 'Pemission Denied' error. This patch serves as
12a workaround to this problem.
13
14Note that this patch doesn't change the logic in the code, it just expands
15the codes.
