No /tmp/fai/, /tmp not writable

[John G Heim]

I'm having a problem with my FAI installs. The target machine comes 
upunable to create a /tmp/fai/fai.log. So I can't really tell where the 
problem begins. If I try to create the directory /tmp/fai/, I get the 
error "Operation not permitted". I would assume that means the root file 
system is mounted read-only.

This may be related to an upgrade I did recently. My FAI server was 
running ubuntu 16.04. I had to upgrade it to 17.10 last week. That may 
or may not have upgraded fai since I get fai from the fai repository 
itself,.

PS: Unfortunately, I cannot tell you what the screen says on the target 
machine. I'm blind. I used my phone to read it to me and it has a a 
gazillion "file not found" messages.
