You are right. I checked (before I sent my mail) `id' under chroot
but I saw that the uid & gid are saved but I failed to see that the
effective user and group (euid & egid) are both 0 (root).

So it seems a pity there is no "user chroot" that restores the user 
uid & gid after changing the "root" but before calling the command.

Ehud.
