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.

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

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.
