Hi all!
Is it just me or can sombody else replicate this behaviour:
1) pmount installed, udisks2 not installed: I get the "device inserted
.."-dialog, but the device icons do not show up. Mounting and unmounting works. After
removing all external devicis I still have /media/ populated with "interesting"
folders, each containing one file ".creaded_by_pmount". Zhese survive a reboot,
so I have to remove them by hand.
2) udisks2 is installed, pmount not instaled: I get the "device inserted
.."-dialog, and all device icons as expected. Mounting and unmounting works. /media/
is working as expected, i.e. folders disappear when the device is removed.
So ... save to say "install udisks2 and forget aboult pmount" ? pmount i used in
exegnulinux, that's why I ran into it.

Hi everyone,
I will reply here although I read the other messages too. I spent lot of time testing with
udisks2 and pmount in my work
on LUKS support.
I assume you are using R14.0.x since you still have the "device inserted" dialog
(not to worry, this will still be there
in R14.1.0 although currently it is not... long story behind it).
udisks2 works like a charm, at least as root. If you are a normal user, you may need
permissions, but that is another
matter. Each operation (unlock, mount, unmount, lock) can be executed individually and
overall there are no issues.
pmount provided partial functionality, as in you cannot execute those 4 operations
individually but only combined. Also
pmount only supports removable devices, while udisks2 works also on internal disks (like
/dev/sdX).
Overall, based on my experience I fully recommend to use udisks2. pmount, udevil, udisks
provide partial or support for
LUKS devices.
Cheers

Hi Michele,
I wanted to thank you for both this post and the last LUKS post you made!
It’s always nice to understand the ‘backend’ of the software we use.
Oddly I though my machine was running udisks2, but it seems to only have
pmount and udevil installed.[1]
Would you have any recommendations on how to add udisks2 and remove pmount,
udevil, and udisks, such that nothing ‘bad’ happens? Or is it safer to just
add udisks2?
Background: I used encrypted removable drives in the past for backups.[2]
When the last one died (year+ ago) I switched backups to ‘tar | gpg’, so I’m
not real sure I’ve used encrypted removable drives on this specific system.
[3]
I’d like to go back to using encrypted removable drives for backups
(definitely easier), so I’m really glad these posts came up identifying I may
not have ‘good’ software installed currently for that.
Again, thanks for you help and knowledge.
Best,
Michael

glad to be of help :-)

You can pretty much have all of them installed, there isn't any conflict AFAICT.
In R14.1.0 udisks2 has the top priority, followed by udisks, udevil and lastly pmount.
tdehw library will use the first
available method that it finds.
I normally have just udisks2 installed, but for testing I experimented with different
combinations and didn't run in any
problem other than the limitations of the various tools. Note that udisks is no longer
available in recent distros,
having been replaced by udisks2.
If you run R14.0.x you won't be able to unlock/lock LUKS disks from the GUI, you still
need to use CLI or D-bus calls to
the backend that you have installed.
Deoending on what is your policy on updates, you may want to consider switching to PTB,
where you can unlock a disk with
a double click + password.
