 # Directories for bind mounts
-Create directories for bind mounts and make them owned by xrootd where nescessary
+Create directories for bind mounts and make them owned by xrootd where nescessary. Here one needs to check that the data directory is the correct path (e.g. the path where the raid system is mounted) and possibly adjust the bind mount in `/etc/systemd/nspawn/xcache.nspawn`
 ```bash
 mkdir -p /var/spool/xrootd /var/run/xrootd /srv/data/xrootd/namespace /srv/data/xrootd/xrdcinfos /srv/data/xrootd/data
 chown xrootd:xrootd /var/spool/xrootd /var/run/xrootd /srv/data/xrootd/namespace /srv/data/xrootd/xrdcinfos /srv/data/xrootd/data
