I don't know why, but on my ubuntu 16.04 laptop,
udisksctl can work properly without
root privilege. However, when I plug this disk to centos 7, the execution of same command needs root privilege and I get:
==== AUTHENTICATING FOR org.freedesktop.udisks2.filesystem-mount-other-seat === Authentication is required to mount Hitachi HTS542512K9SA00 (/dev/sdc1) Authenticating as: root
I wonder why the same command executes differently on these two system, and how can I get rid of the privilege check?
