Hello,
Can anyone please tell me whether guestfish can mount exFAT partitions?
I created a full disk image of a drive which contained a single exFAT partition.
Was able to mount it with kpartx/FUSE:
# kpartx -a -v disk.img
add map loop0p1 (252:2): 0 39070078 linear 7:0 2
# mount /dev/mapper/loop0p1 /mnt -o ro
FUSE exfat 1.2.3
# ls /mnt
foo bar baz etc
but not guestfish:
$ sudo apt install libguestfs-tools
$ guestfish --version
guestfish 1.32.2
$ guestfish -a disk.img
...
<fs> run
...
<fs> list-filesystems
/dev/sda1: exfat
<fs> mount /dev/sda1 /
libguestfs: error: mount: /dev/sda1
on / (options: ''): mount: unknown filesystem type 'exfat'
<fs> q
Results identical under both Linux Mint 18 and Fedora 24 (which was running a slightly
newer version of guestfish, 1.34.2).
Sincerely,
Miles
P.S. I read about installing libguestfs-winsupport for NTFS in the FAQ, but it appears to
only be for RHEL: https://access.redhat.com/discussions/623573#comment-595723

guestfish or libguestfs don't support filesystems. It's whatever
is supported by the kernel.
exFAT is apparently not supported by the Linux kernel, but there is a
FUSE driver for it called exfat-fuse (as you found out).
So if you add exfat-fuse and maybe exfat-utils to the appliance,
it should work, ie:
# echo exfat-fuse > /usr/lib*/guestfs/supermin.d/zz-exfat
# echo exfat-utils >> /usr/lib*/guestfs/supermin.d/zz-exfat
(Note the package names might be different. Apparently in RPMfusion
it's called fuse-exfat.)

Awesome! Thanks very much Rich. That worked perfectly!
In Fedora 24 x64:
# echo fuse-exfat > /usr/lib64/guestfs/supermin.d/zz-exfat
# echo exfat-utils >> /usr/lib64/guestfs/supermin.d/zz-exfat
In Linux Mint 18 x64:
# echo exfat-fuse > /usr/lib/x86_64-linux-gnu/guestfs/supermin.d/zz-exfat
# echo exfat-utils >> /usr/lib/x86_64-linux-gnu/guestfs/supermin.d/zz-exfat
$ guestfish -a disk.img
<fs> run
<fs> list-filesystems
/dev/sda1: exfat
<fs> mount /dev/sda1 /
<fs> ls /
foo
bar
baz
etc
Gratefully,
Miles

Thanks for testing. I've just posted a patch so we can include
this upstream.

Right on - thanks very much!
And thanks for the shout-out in the patch notification - you are really
too kind in even mentioning me, as you certainly did all of the work.
Just added guestfish to this old guide I cobbled together 5 years ago:
Mounting partitions from full disk images
https://tinyapps.org/docs/mount_partitions_from_disk_images.html
My apologies for not having added it sooner!
Aloha,
Miles
