A few loaders use loaderutil.add_virtual_ntfs_filesystem() to add a virtual NTFS filesystem. When using this functionality, a "fake" NTFS filesystem is added. This filesystem contains references to the $MFT, $UsnJrnl etc. This filesystem is used for NTFS-specific plugins. The added "fake" virtual NTFS filesystems can only be used by plugins, not for mount points.

When using target-mount on a target for which loaderutil.add_virtual_ntfs_filesystem() is used, this leads to entries in fs/$fs$/ . This issue is reported as issue #1457.

However, it also leads to entries in filesystems (such as filesystems/fs_1).

Target-mount should create mounts in filesystems/ for the virtual filesystems which have a "fake" NTFS filesystem attached. It should not create mounts in filesystems/ for these "fake" NTFS filesystems themselves.
