pg_standby testing notes

I am looking into using pg_standby (v3) in a warm standby system. I'm
going to double check it, but same machine replication seemed to work
ok. When I tried to do remote server log shipping however, I had some
issues.

Initial setup and launch is working ok, my archive command is:
'test ! -f /var/lib/pgsql/pitr/%f && cp %p /var/lib/pgsql/pitr/%f'

my restore command is:
pg_standby -m -t/raid/pitr/kill /raid/pitr %f %p

'/raid/pitr' is an nfs mount mounted from the primary to the standby.
I suspect the problem lies there, but I thought I'd ask. here is my
log on the standby following a fresh pitr load:

neither the primary or the standby are in production...the 3 restored
files were from me manufacturing work on the primary to generate
files. Is there anything obvious I should be checking?
