Ubuntu is apparently failing to correctly setup exFAT support after installing the exfat-fuse and exfat-utils dependencies.
exFAT is nowhere listed on filesystems sources. Any idea on what is going on? Am I missing something?
$ apt-cache policy exfat-fuse
exfat-fuse:

Issue solved. Forgot to specify the volume offset (
mount -o offset=byteoffset) in the image while mounting, which explains why the filesystem was not being found.
