However, what happens in 156 is weird: I can change the names in Mount Manager as normal, the new name is then shown in Menu/Information/Network as the correct host name - but Network Browser only finds each box as 'tm-twin-oe' (with the correct IP for each box)!
The host name has nothing (or little) to do with Mount Manager. It's a network concept (it's really the name of the network interface - you can have multiple interfaces each with different names, but with just one you'd usually use the hostname). So you'd need to configure it somewhere else.
Or, if it's easier than finding the place in the menu. edit the
/etc/hostname file appropriately and reboot. This file is normally backed up, but since you will have gone to 156 with no restore you'll have lost the "correct" settings.
I also lost such a setting - as the
/etc/fstab file also went back to a default setting. Whereas all seemed to be OK after the update a day ago, when I looked this evening there was a message on the front panel about a "Write error". I couldn't find anything in logs but then, to my surprise/horror I only had two recordings under
/media/hdd/movie as well - both from today! All other recordings had gone.
This seemed a little odd - particularly as
df showed that my 1.5TB disk was still >30% full.
Ieventually worked out that my USB stick was now mounted as
/media/hdd, and the hard disk as
/media/sd?1. I seem to recall that I had a similar problem when first inserting the USB stick. For some reason the USB stick gets mounted as a hard disk, and I had to sort this out with the Mount Manager. I was able to sort it out again and move files to correct locations. Also the two recordings that had failed through lack of space were fetchable from the BBC iPlayer, so I haven't missed anything.
However - it strikes me that
both of these items (hostname and disk-layout) should be items that are handled by the first-time setup wizard.
