 # /etc/condor and /direct/condor are necessary bind mounts for BNL
 # * Make a symbolic link between installation <...>/etc/grid-security and actual directory /etc/grid-security
+# * SDCC host Python ABI compatability:
+#     - libcrypt.so.1 symlink pointing to libcrypt.so.2
+#     - libcrypto.so.10 symlink pointing to libcrypto.so.3
+#     - libssl.so.10 symlink pointing to libssl.so.3
 # * Make "analysis-systems" kernel discoverable to BNL SDCC which has kenerls at /u0b/software/jupyter/kernels/
 # * Ensure default directories and that they are writeable by arbitrary user
 # * Set defaults for jupyter lab
 # * Set JUPYTER_PATH and JUPYTER_DATA_DIR
 # * Add build date file to easily check if analysis facilities have synced images
 # * Add bind mount to Lustre space at BNL SDCC
-# * Symlink condor binaries under /usr/bin/ to ensure available globally
