It looks like we have a problem running preflight on LN OSS builds, which is impacting Dataland and now the UK env.

For example, in dataland, from either http://10.241.3.241 or http://10.241.3.242 (both running LN OSS 3.4.2) and preflight nodes running the same build, it returns the following error:
System command(s) has been executed. Response: usage: //sbin/preflight dir command

Watching the /var/log/secure file when running preflight against the same node and I see it is coming in as root, which I know under 702 it should be coming in as espuser… not sure if that is part of the problem:

Jan 31 10:18:50 BOCA003242 sshd[28641]: Accepted publickey for root from 10.241.3.242 port 38342 ssh2
Jan 31 10:18:50 BOCA003242 sshd[28641]: pam_unix(sshd:session): session opened for user root by (uid=0)
Jan 31 10:18:50 BOCA003242 sshd[28641]: pam_unix(sshd:session): session closed for user root

Here is what we were able to capture from the logs showing that the esp is dropping the path to the esp instance in this case:

[root@BOCA003242 esp]# grep preflight ./*log
./esp_main.01_31_12_10_33_58.log:00000194 2012-01-31 10:34:01 29795 29807 "command_line=ssh -o StrictHostKeyChecking=no -o ConnectTimeout=5 10.241.3.242 '//sbin/preflight eos_infiniband_esp' 2>&1>"
./esp_main.01_31_12_10_33_58.log:00000195 2012-01-31 10:34:01 29795 29807 "response=usage: //sbin/preflight dir command
./esp_main.01_31_12_10_33_58.log:Response: usage: //sbin/preflight dir command/td>
