Udisks uses ntfs instead of ntfs-3g

Udisks uses ntfs instead of ntfs-3g

Udisks mounts external NTFS partitions using the NTFS kernel module
(read-only) instead of ntfs-3g (read-write).  I would assume that if the
users have ntfs-3g installed, they probably want to use it by default

I haven't tested it, but I think symlinking mount.ntfs to ntfs-3g is
enough to get Udisks to use ntfs-3g by default.

(It's what https://wiki.archlinux.org/index.php/NTFS-3G seems to suggest
at least.)

What do you think?

The change would be fine by me, but perhaps it would make sense to
discuss it with upstream Udisks people?

I also noticed that Guix packaged version is 2.1.8 which is fairly old.
Latest release is 2.7.6.

I can submit a patch.

Please do.

I've patched ntfs-3g to symlink mount.ntfs to mount.ntfs-3g and it works
as expected.  If the new ntfs-3g is installed as a system package, that
is to say.

Indeed, libmount seems to only look in

	/run/current-system/profile/sbin/mount.*

and not in

	~/.guix-profile/sbin/mount.*.

Is this the behaviour we really want?  Maybe, considering libmount is fairly
low level.  Any insights?

To see that you can try the following command:

--8<---------------cut here---------------start------------->8---
> sudo LIBMOUNT_DEBUG=all mount /dev/sda1 /mnt
5132: libmount:     INIT: library debug mask: 0xffff
[...]
5132: libmount:      CXT: [0x2162690]: /run/current-system/profile/sbin/mount.ntfs ... not found
[...]
--8<---------------cut here---------------end--------------->8---

See https://github.com/storaged-project/udisks/issues/532 for more
details.

I'll submit a patch soon.

Nice!

Does libmount provide any run-time control over how it finds these
things?  For example, is there an environment variable or a
configuration file that controls where it looks?  If so, we might be
able to customize it, or at least a user might be able to use it to tell
libmount where to look.  I don't know much about libmount currently,
which is why I'm asking.
