Automouter, hide partitions
 
Hello,

I have Fedora 9 installed on my pc.
I also have Fedora 8 installed.

Both are on extended partitions.

when I start F8 I have the partition of F9 "automounted".
And when I start F9, I have F8 also "automounted".

I use automounter (autofs), because it is handy for CD, USB etc.

I have a common partition (extended) to share data between F8 and F9.
For this partition I MUST see it in both.

How/what can I do that I do not see the other operation system, only the shared data-partition?


thanks

You probably have the other partition specified in your /etc/fstab file on both systems. Take a look in /etc/fstab and comment out any entries that you do not want mounted at boot.

P.S. Instead of commenting an entry out you might add the "noauto" option to stop automounting the partition.

I did some more investigations :

What happens ?

When I start Fedora 9 in runlevel 3 I do not get any harddisk partitions "automounted"/

When I start afterwards X (going to runlevel 5) I get a lot harddiskpartitions "automounted" to /media/ *

I do not find any entry for it. Not even in /etc/auto.master

Can someone explain me why/how this happens ?

And how can I prevent this from happing? (so that the harddiskpartitions are not more "automounted" on start of X)

What I seen in runlevel 3 :
Code:
