So, the captured output shows me that nail is not starting at all. My 
init.d script calls mailtext.sh and both write logger statements that I 
see in /var/log/messages. During startup and shutdown I see all these 
messages, but no nail output. If I run any of the scripts, once logged 
on via ssh as root, then everything runs OK.

Can this be a permissions thing? Under what user do the init scripts 
run? Nail executable has 755 and root:root.

I am calling nail giving it its full path, so I assume that is not a 
problem, I would have expected some kind of output if that had been the 
problem. Hows about nail not boing able to find any .mailrc file?
