# 1) BOUND doesn't always set hostname (e.g. if old_host_name is unset in

|
# precise pangolin)
|
|
# 2) Using too long of a FQDN as a hostname causes some tools to break in
|
|
# some distros (e.g. ssh-keygen) and hostname tool complains when given
|
|
# a FQDN that is > 64 bytes.

# As a result, we set the host name in all circumstances here, to the truncated
