Are you sure that it is the existence of the a user's ACL permission which prevents the other's from ejecting and not their lack of own permission ? I understand from traces in the web, that on my Debian Jessie it is about SUBSYSTEM=="block", ENV{ID_CDROM}=="1", TAG+="uaccess" in /lib/udev/rules.d/70-uaccess.rules Rumor has it that "uaccess" causes the ACL. The permission set of my /dev/sr0 brw-rw----+ 1 root cdrom 11, 0 Dec 23 12:26 /dev/sr0 is not narrowed by the desktop user's ACL but rather widened. So i would assume that your whole family needs rw-permission. That could be achieved here by putting them all into group "cdrom". Have a nice day :) Thomas
