It looks like our FAQ needs to be updated. I think that question was
written in pre-TM-boot-module days.
However, even if you specify $PBS_NODEFILE with lamboot, the tm boot
SSI will ignore it. So it's harmless. You might want to read the TM
boot module writeup in the LAM User's Guide. This is perhaps the most
definitive source of information for users.
You did not answer my question, however:
>> Question: are you invoking lamboot in a PBS (Torque) job? The TM

The fact that you are trying to use $PBS_NODEFILE implies that you're
inside a PBS job, but the error message that you sent in your previous
post:
>>> n-1<28345> ssi:boot:tm: not running under PBS
implies that you were trying from outside a PBS job (which is why the
tm boot module disqualified itself). Have you tried lamboot -d from
*inside* a PBS job?
