   You can on a native Linux system, but we’re trying to get to that.

   A load of crap, in other words.

   But maybe not skilled enough. Does “lsblk” work? Does the content of   
   /proc/self/mountinfo show anything sensible?

   So much for being “skilled”, eh?

   That’s not how you normally query what’s mounted. Try the “df” command.

   You might be right.
