Andreas Roth's questions

I have set up two directories mounted with automount (via LDAP):

in the /home directory automount is configured to mount

*   -fstype=bind :/network/srv/home/&

in the /network directory one entry

srv    -fstype=nfs4,rw,sec=sys,noatime,hard,intr,proto=tcp,timeo=100,port=2049 myserver:/

when i try to access the home directory of a user (e.g. ls /home/myuser), automount fails with the error message:

>> mount: special device /network/srv/home/myuser does not exist
failed to mount /home/myuser

when i do the 'bind mount' manually using

mount -o bind /network/srv/home/myuser /home/myuser

automount for /network/srv is triggered and the myuser home directory is successfully mounted to /home/myuser.

Any ideas how to tell automount to load the /network/srv before trying to mount /network/srv/home/myuser???

On my system i have windows 7 and ubuntu 10.04 installed.

I need to share large amounts of data between both OS. My idea is to set up a partition which both system can access and exchange data. Any suggestions which filesystem to use for this?

I have a machine (with mythtv installed) which automatically login a user, whose home directory is located on a server accessed by NFS4. In about 6 of 10 times it works like a charm, but sometimes the login stops because the home directory is not yet accessible. The home directory mount is mananged by autofs (using LDAP) and NFS4 on client and server (running Ubuntu 10.04). Any ideas, how to configure 'wait until home is ready' for my auto-login?

Is the portmap service required on a ubuntu machine - when i'm using NFS4 mount only - when i'm exporting files using NFS4?
