[slurm-users] job_container/tmpfs and autofs

[Gizo Nanava]

Hello, 

another workaround could be to use the InitScript=/path/to/script.sh option of the plugin.

For example, if user's home directory is under autofs:
script.sh:
uid=$(squeue -h -O username -j $SLURM_JOB_ID)
cd /home/$uid

Best regards 
Gizo
