prompt: We are currently solving the following issue within our repository. Here is the issue text:
  --- BEGIN ISSUE ---
  Histo dataset mounting script does not show files permanently
  Files are only visible while the script is running, but disappear once terminated. 
  This could be a consequence of the library updates in #455.
  
  --- END ISSUE ---
  
  Below are some code segments, each from a relevant file. One or more of these files may contain bugs.
