I don't understand that either. Well, it's just one thing actually: it looks 
as though the remote mount still isn't right, so that some transfers just seem 
to vanish down a black hole.

Now I have the NFS mounting working, apparently, with no reported errors, but 
I still can't get the combined system to behave. I mount the i5's portage tree 
and packages directory on a partition on the M9, chroot into it, 'env-update 
&& . /etc/profile' and attempt to 'emerge --sync' (this is using the Git 
method).

Everything starts to go well, and gkrellm on the i5 shows plausible network 
traffic on both machines - but no disk transfers. This goes on for a couple of 
minutes until I give up.

Before starting any of that I recovered a backup of the i5 and untarred it 
into the chroot partition; not the whole thing, just the root FS and /var, 
which I've kept separate for many years. Oh, and /usr/local. The backup was 
just two days old.

While bug-hunting, I created two new partitions on the i5: one each for the 
portage tree and the packages directory. That was to eliminate the possibility 
that the NFS mount was failing because it wasn't at a file-system root.

Also while bug-hunting, I found an extra-long Ethernet cable and strung the i5 
into the LAN that way. The M9 only ever sees the LAN, whereas I can now start 
and stop the LAN and WLAN at will on the i5. The Fritz!Box router sits at the 
junction. Eventually, of course, once I get this setup working, the cable will 
go back in the cupboard.
