[Description Jakub Jozwicki 2005-09-03 04:22:08 UTC]

mount /dev/sda1 /mnt/sda1
mount --move /mnt/sda1 /tmp
mount:
"/dev/sda1 on /mnt/sda1 type jfs (rw)
/mnt/sda1 on /tmp type none (rw)"

Old mount entry is not removed, and new has invalid filesystem type.

Steps to Reproduce:
1.emerge gentoo-sources-2.6.13
2.mount /dev/sda1 /mnt/sda1 && mount --move /mnt/sda1 /tmp
3.mount

Actual Results:  
Old mount entry is not removed, and new has invalid filesystem type.

Expected Results:

the --move worked correctly, util-linux just didnt properly update the mtab file

look at /proc/mounts and you should see that everything is in order
