Re: [HTCondor-users] TMPDIR variable in singularity

[Matthias Schnepf <matthias.schnepf@xxxxxxx>]

I looked a bit into the HTCondor code. At 
https://github.com/htcondor/htcondor/blob/dfc8116de7f4617fc06b21898c3722dedffcfd86/src/condor_starter.V6.1/singularity.cpp#L207 
some variables are updated. I added the code to update the $TMPDIR 
variable like the others and tested it. The variable changed inside the 
singularity container. I used singularity version 2.5.2.

Regards,

Matthias
