I do not know whether anything else is run directly from the DVD.

I forgot that not every user knows the root password. Remounting
without noexec might be tricky. For instance, in RHEL4 default
configuraton, /etc/fstab is modified by hal daemon and DVD is
automatically mounted by gnome. The user can disable automounting in
his or her gnome preferences but hal daemon can be stopped or
reconfigured by root only. Thus it seems to me as the best solution to
copy lzmadec as well as other executables needed during installation
to some temporary directory, e.g. texmf-var/tmp, and run them from
there.
