# HACK: manually configure the INTEL_MIC_FS
# We do this because we need /opt/intel/mic/filesystem to be a writeable directory
# so that the micX.image can be rebuilt when MPSS starts.
# We also need to configure per-node entries in /opt/intel/mic/filesystem/micX/.
# So we manually configure the /ram softlink here.
# We also install the code that will install the /opt/intel/mic/filesystem in /ram.
# The reconf-diskless-snapshot.sh script will create the per-node entries.
