The partitions are still mounted. I think Mar 26 was the day I installed fc8 from the liveCD and did "yum update". If I gave me that privilege, I don't remember (not at all surprising). I guess I can add a "cd /media" "sudo umount *" to rc.local or somewhere. Not very elegant, but so far I can't find any comprehensible (for a user) documentation on where or how this stuff is controlled. In /etc/PolicyKit/PolicyKit.conf, I have <config version="0.1"> <match user="donvogt"> <return result="yes"/> </match> </config> Which I got out of the manual. I suspect that has the effect of turning off whatever controls PolicyKit is trying to control. In my case that may be OK since I am the only user (until I get rootkited). Thanks for the help.
