I have a big USB disk with 3 partitions: one for backup and two other bootable ones for installing and testing new distros. I want the backup partition automounted on boot. But I don't want the two test partitions automounted. Despite my use of "noauto" in /etc/fstab, something (gnome?) seems to be mounting them when I plug the drive it.

LABEL=mybook            /srv/backup     ext4    defaults        0       2
LABEL=mybook-root       /media/mybook-root ext4    user,noauto  0       2
LABEL=mybook-spare      /media/mybook-spare ext4   user,noauto  0       2

In previous Ubuntu distributions it seems that it was possible to configure gnome so it would avoid mounting particular partitions on removable drives like USB:

gnome-mount --write-settings --mount-options noauto --device /dev/sda1

This is no longer available in Lucid (when did it go away?)

Is there another way to do this now?
