I agree, I though it good not having X11 programs in the PATH when I was using the TUI interface only. >> About that not looking all bad, perhaps the merge should be in the other >> direction, from /usr to / rather than from / to /usr.

Net-boot systems need a / filesystem anyway, that it's merged with /usr or not. In the case of a partial net-install, / is local and /usr (as well as /home) is remote. In this case in the local / you have everything you need to configure the network and to install /usr over it. In the case of a full net-install, you have to mount the / filesystem over the network, which again will have everything needed to mount any additional filesystem over the net, /usr included. It's not that complicated, in both cases you just need the relevant scripts and config files on the / filesystem that it was local or mounted over the network. LTSP and DRBL have been doing this for many years. You actually have a bonus if you don't do the / -> merge, that is you could have separate / filesystems for different clients that are going to boot over the network (with different settings in /etc, for instance) while they're going to be served all the same /usr filesystem, which is going to simplify the overall NFS layout. >> So, I'm against a *forced* /usr merge.

This could happen, but I don't think is going to be a major hassle.
