[Bug 1762920] Re: casper-helpers:try_mount doesn't honor the mount point

[Tomo]

** Description changed:

  I apologize for direct mentioning to the source codes.
  Problem:
-  try_mount() in casper-helpers script doesn't honor the mount-point parameter when mount-option != "ro".
-  This is obvious on code, but it wouldn't what it meant to be.
-  I guess,
-    if the device is already mounted on A, and
-      if the indicated mount point of which is the same as previous mounted (i.e. A; where_is_mounted() says),
-       do  mount -o remount ...
-    else
-       do  mount -o bind ...
-    whatever the indicated mount options are.
+  try_mount() in casper-helpers script doesn't honor the mount-point parameter when mount-option != "ro".

-   This spec suffers in the case, 
-    setting persistence YES, boot media, especially USB, is multi-partitioned, and persistence data are on separated part from the base boot image.
-       In that case, find_cow_device() falsely unmount /cdrom (because where_is_mounted() says '/cdrom' was
-    previous mount point in the device searching iteration) and gone busybox prompt.
-   There might be a fix find_cow_device() itself but, I thought that try_mount() is fundamental.
