From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.3a) Gecko/20021212 Description of problem: If you attempt to umount a partition that you don't have permission to unmount then you normally get a message like "umount: only root can umount ..." but I get gibberish instead of the user name. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. umount /boot (as an ordinary user) 2. 3. Actual Results: umount: only U???\??? can unmount /dev/sda1 from /boot on one system (resierfs) and umount: only ???????? can unmount LABEL=/boot from /boot on another (ext3 this time). Expected Results: I get this on a 7.3 system: umount: only root can unmount LABEL=/boot from /boot Additional info: This is mount-2.11r-10
Could you try the latest mount package (rawhide preferably, but RHL9 should work) and see if the problem goes away?
On shrike with mount-2.11y-9 I get the message umount: only root can unmount LABEL=/boot from /boot which would seem to be right and suggests that the problem has been fixed.
