[HTCondor-users] Master Shutdown From Startd Cron

[Laurence <lfield@xxxxxxx>]

Hi,

I am setting a boolean variable using a Startd Cron and would like this 
to be used in the Master Daemon Shutdown expression. The boolean 
variable is MULTICORE_SHUTDOWN and returns either "true" or "false".

The cron is working and I can see the variable being set correctly in 
the MachineAd.  The Master is shutdown correctly if the shutdown 
expression is explicitly set to "true".

MASTER.DAEMON_SHUTDOWN = true

However I have tried the following to include the variable but none seem 
to work.

MASTER.DAEMON_SHUTDOWN = ( STARTD_MULTICORE_SHUTDOWN =?= true )
MASTER.DAEMON_SHUTDOWN = ( MULTICORE_SHUTDOWN =?= true )
MASTER.DAEMON_SHUTDOWN = ( MULTICORE_SHUTDOWN == true )
MASTER.DAEMON_SHUTDOWN = ( $(MULTICORE_SHUTDOWN) == true )

What would the correct expression be or is this not possible?

Thanks

Laurence
