automount of secondary hard disks / partitions: new?

[Gianluca Cecchi]

Hello,
I have fc5 devel root on /dev/sdb2 and I noticed that it automatically mounted
my first disk's partitions, and my other /dev/sdb1 partition, also
creating mount points,
with the names below...
I'm sure few days ago the behaviour was not this

[gcecchi at fedora ~]$ df -k
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/sdb2             11337596   8464660   2297008  79% /
/dev/shm                515672         0    515672   0% /dev/shm
/dev/sda1               101086     32525     63342  34% /media/disk
/dev/sda3             49224744  43782308   4442232  91% /media/disk-1
/dev/sda5             68326840  61769756   5168748  93% /media/disk-2
/dev/sdb1              3142552   2841328    301224  91% /media/disk-3

Where do I find config choices/settings for this? Such as mount-path,
rw/ro mounting, ecc?
I searched in autofs and udev but I seems not to find anything useful?
Thanks
Gianluca
