This patch has fixed /usr/sbin/ltsp-update-kernels for me so I no longer have to specify the location of the chroot. Find doesn't seem to like it if you specify /opt/ltsp as the path to find from, but is fine with /opt/ltsp/ or /opt/ltsp//, so I figure it's safe to append a trailing slash to the find command.
