Hi,

I'm running a local singularity image in a dirac job, this job runs fine on `LCG.UKI-LT2-IC-HEP.uk` but when on `CLOUD.UKI-LT2-IC-HEP-lz.uk` I get a container creation failed:

Error message:
```
INFO: Converting SIF file to temporary sandbox...
FATAL: while extracting hyper_lite__0_1.sif: root filesystem extraction failed: extract command failed: FATAL: container creation failed: multiple devpts instances unsupported and /dev/pts configured
: exit status 255
```

This is my singularity command (mounting current working directory, x509 proxy location and cvmfs):
```

$SINGULARITY_BIN run --contain 
            --env X509_USER_PROXY=${X509_USER_PROXY} \
            -B $PWD -B $X509_USER_PROXY -B /cvmfs \
            $LOCAL_IMAGE /bin/sh -l $JOB_SCRIPT

```

Also by default i'm using `/cvmfs/oasis.opensciencegrid.org/mis/singularity/current/bin/singularity` for the singularity binary, unless user namespaces aren't enabled on that system and then it uses the local singularity instead.

I wonder if the issue is with something i'm mounting or is it something else?

Thanks,

Andrew
