Re: [HTCondor-users] preserve on/off state over restart

[Pek Daniel <pekdaniel@xxxxxxxxx>]

Hi,

I'm just wondering: isn't there some way to have a hook script or
command which automatically runs whenever a daemon starts/stops? Or
whenever condor_on/off invoked? I'd like to put down on the filesystem
some kind of flag-file which I can use after a reboot/restart to
recover the last known state (on/off) of a daemon...

Thanks,
Daniel
