'narcissus' Image builder, and web browsing

Hi All,

I have been trying various configurations, most of which have worked
without any issue.

So far I have had no luck getting Firefox or Epiphany web browsers
running - the issue may relate to the app trying to create file(s) on
a read only file system.

I assume I have to somehow point these apps at RAMSDISK, or create a R/
W partition on the SD cards

Ping works fine, so I am pretty sure that network connectivity is OK,
and I can see a TFTP server running from a remote machine.

Any help appreciated.
