Subject: [PATCH] Add NTFS support to 90dmsquash-live module
Support booting from USB media with NTFS filesystem (optionally),
which removes the FAT32 related 4 GB file size limit for LiveOS/
squashfs.img (and any other file on the same USB media).
Backports 37437cac8a1f2c411ead5fca28fb743a6f36f912 from dracut 046
