On the client side, I started a nbd-client daemon. I did mount the nbd device. Then, I added a file in the client root and regenerated the image. The nbd device is still mounted on the client side. When the image building was over, I got this line with lsof : nbd-serve 10575 nobody 4r REG 8,2 150245376 930291 /opt/ltsp/images/i386.img (deleted) The added file didn't appears on the client side. It seems that the file is replaced, but since it's beeing used and open by a process, the kernel doesn't flush the file until no more process is using it. Until all nbd-server process using a specific image file exits, the space will not be released, so that's why if you rebuild the image while beeing in use it appears to lower the available space. So, thin-clients will behave correctly if you rebuild the image. Thin-clients have to be rebooted to use the newer image. If you change often things in the client root, I found it anoying to rebuild each time the squashfs image. I did revert to NFS. https://help.ubuntu.com/community/UbuntuLTSP/LTSPWithoutNFS But there is a bug with ltsp_config from gutsy that prevent correct behavior.
