CUPS won't start on fat client

I was able to get root access by doing

$ sudo chroot /opt/ltsp/amd64 passwd -u root
$ sudo chroot /opt/ltsp/amd64 passwd

and setting the password. As I guessed, cups isn't starting. In fact,
when I look in the rc.d directories, all mentions of cups are K50cups
files, meaning that cups is getting killed, rather than started.

Once I start cups manually, using the root account on the client, then
login in as a normal user, everything works fine. There's something
funky about trying to install cups in a chroot. Because the
installation script tries to run the cups server as part of
installing, and fails because it's in a chroot, the cups daemon
doesn't get set up to start on boot.

Any ideas?
