I didn't understand why ltsp-pam places his files in
"/opt/ltsp/i386/opt/ltsp/i386". It should be "/opt/ltsp/i386".
$ tar xzvf ltsp-pam-0.77-0-i386.tgz -C/home/pvpy
This is indeed a bug, and will hopefully get addressed when we build the next
update (real soon now)
This has been fixed, and it's in the CVS repository.
