dist-upgrade of chroot

This is on Edubuntu Gutsy.

I wanted to enable vnc[1], but my chroot only had a cdrom for
sources.list.  So I copied the sources.list file from the server to
the chroot, and then ran a dist-upgrade.

Then I got a few errors:

    Can not write log, openpty() failed (/dev/pts not mounted?)

In addition to chroot /opt/ltsp/i386 do I need to mount /dev/pts in
general?  Same with /proc?

Also, a new kernel came with the update.

Preparing to replace linux-image-2.6.22-14-386 2.6.22-14.46 (using .../linux-image-2.6.22-14-386_2.6.22-14.47_i386.deb) ...
Unpacking replacement linux-image-2.6.22-14-386 ...
Examining /etc/kernel/postrm.d .

So, what needs to be resolve there?

Wouldn't ltsp-updte-kernels need to be run after installing a new
kernel in the chroot from *outside* the chroot?

[1] Btw, shouldn ltsp-update-image be run after modifying the chroot
on https://wiki.edubuntu.org/InstallX11VncOnLtspClients ?
