Now, I moved the mount-point (from /mnt/home2) to /home2 and add the following line in /etc/ltsp/ltsp-update-image.excludes: home2/*
The good news is that the mount-point is now visible also at the client side. However, the symlinks still do not work because nothing is mounted to /home2 yet. I've tried to get more information about the parameter LOCAL_APPS_EXTRAMOUNTS=/home2 ...and found a link which explains that the extra mount (=/home2) will be mounted (to the client) only if the mountpoint in the chroot (=server) is empty ... which means that the idea of the parameter LOCAL_APPS_EXTRAMOUNTS is to share the same (empty) folder to several clients (e.g. for file exchange ...?) (see https://help.ubuntu.com/community/UbuntuLTSP/FatClients) Since my folder /home2 contains subfolders of all users (containing their Virtualbox stuff) the above mentioned approach will not help. For that reason I will try to implement Helmuts idea, which might take some time. Further comments are welcome ...
