Hello,

When I try to mount an external USB drive using udiskie-mount from
inside a cron job, I get an error as follows below. Using
udiskie-mount directly from the command line works fine.
<snip>
From a big picture perspective, I don't really understand why
mounting directly from the command line is treated differently
from a cron job. Can someone enlighten me?
polkit is treating “local users” and “active local users” differently
(precisely so that users who are physically able to insert or remove a
disk can mount/unmount it). A cron job is, I expect, classified as
neither a local user nor as an active local user.
I’m afraid I don’t think there are standalone format validators /
testing tools for the permission files; check system logs, and output of
polkitd to stdout/stderr (running it without --no-debug, and perhaps
with G_MESSAGES_DEBUG=all in the environment).
I got a working version of permissions to allow `udiskie-mount` and
`udiskie-umount` to run inside a cron job. The file location is
`/etc/polkit-1/localauthority/50-local.d/10-udiskie.pkla`. The contents
are:
[udisks2]
Identity=unix-user:faheem
Action=org.freedesktop.udisks2.filesystem-mount-other-seat;org.freedesktop.udisks2.filesystem-mount
ResultAny=yes
per comments by Thomas H (the udiskie maintainer) - see issue 102 below.
Are both these actions needed? Comments welcome.
See also, the question I asked on unix.stackexchange.com, namely
https://unix.stackexchange.com/q/277606/4671, and the later part of the
Github udiskie issue https://github.com/coldfix/udiskie/issues/102.
I submitted a wishlist bug report to the Debian udiskie package about
mentioning policykit, namely
http://bugs.debian.org/822209. The maintainer asked for a patch.
I opened issue https://github.com/coldfix/udiskie/issues/111, including a
suggested patch. Comments and suggestions for improvement are welcome.
