Well, my Kindle recently took to claiming to be an internal device, so it doesn't get automounted and udisks2 wanted sudo to mount it!

(But calibre still mounts it for me, so I don't care anyway.)
And despite the ridiculous move of media devices to weird obscure directories, I added the following udev rule:
Code:
[eschwartz@arch ~]$ cat /etc/udev/rules.d/99-udisks-fix-media.rules
ENV{ID_FS_USAGE}=="filesystem|other|crypto", ENV{UDISKS_FILESYSTEM_SHARED}="1"
Which I think is also automatically used on Ubuntu (intelligent policy choice). That should cover the common non-techie case. EDIT: Or they just stuck with old udisks1 for a really long time.
If not, well, I cannot make ALL the disclaimers, it would take too long.
