This is really weird...
Here I can use Clonezilla live 1.2.8-23-i686 to sshfs my squeeze server,
using the TUI (prep-ocsroot).
Besides, you mentioned that you can manually issue the sshfs command to
mount your ssh server, so I guess mabye the issue is in the command
prep-ocsroot.
If I can reproduce the problem here, it will be easier for me to fix
this issue.
