How to loop mount mounted BDE volume on Mac OS? #43

Closed michelbehr closed 5 years ago

michelbehr commented 5 years ago

In the Mounting manual it says that all you have to do after using bdemount to mount is to do a "loop mount". But it doesn't work on MacOS, the system requires the specification of the type with -t option, and when I do specify, it says "Block device required". What do I do now?

(BTW: Shouldn't those details be described in the Mounting manual page? Is anyone being able to do this loop mount without specifying type? I'm confused...)

By the way: loop option doesn't work, see below.

michels-MacBook-Air-4:libbde-20190701 michelbehr$ sudo mount -t ntfs -o loop,ro /Volumes/Pendrive/bde1 /Volumes/NTFS/
mount_ntfs: -o loop: option not supported

What specifically should be described? How to loop mount on the operating system of your choice? That is infeasible.

Since you're running on macOS you likely need to run something similar to: hdiutil attach -imagekey diskimage-class=CRawDiskImage /Volumes/Pendrive/bde1

marking as invalid since issue seems to not be an issue in libbde/bdemount, but related to on how to use loop mount functionality of macOS

IMHO the documentation is part of the system. The command you mentioned (which works - thanks!) should be included in the Mounting manual. Yes, I'm using MacOS, and there are OS specific instructions in the manual, this would be an additional one (i.e., if you are running Linux, use this "loop" command, if you are using MacOS, hdiutil command is the way to go).

Yes, and MacOS has documented its usage of hdiutil. IMHO this is basic knowledge of your system, not something this project needs to reproduce.

Also, too many operating systems with too many variations, which makes it infeasible and too time consuming to maintain.
