I'm not sure I saw that hit the list. Are you sure you sent it?

I had to make a few tweaks to get that script to work (e.g., change
$root and the getpwnam argument). Even after doing so, I didn't have
much luck getting a chroot environment. The chroot function says that it
is restricted to the superuser which may be why I'm not seeing much
change as I'm running it under my login. If I use sudo to run it, the
script dies at line 28 (getpwnam).

What does that command do in Busybox? In bash, it generates an error
message.

Who is user 500? tomcat?

I must not be following you where. You've created a chroot environment
that contains an /out directory owned by tomcat. This user has the
permissions to write to the /out directory. Are you asking why the user
was able to create the directory in the first place?
