"inside"? Suse 9.2 is the guest, I don't know whats "inside" or "outside"!
Suse 9.2 runs in its own namespace. The partitions (drbd-devices) of
Suse 9.2 are also mounted in the host, thats all:
haupt1 is the host:
===================
haupt1:~# mount
/dev/md0 on / type ext3 (rw,noatime,errors=remount-ro)
tmpfs on /lib/init/rw type tmpfs (rw,nosuid,mode=0755)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw,noexec,nosuid,nodev)
procbususb on /proc/bus/usb type usbfs (rw)
udev on /dev type tmpfs (rw,mode=0755)
tmpfs on /dev/shm type tmpfs (rw,nosuid,nodev)

.. hmmm: no acl option shown here ...
The partitions are mounted here because they're exported by NFS,
client are DLC's (diskless clients) that mount the /data/pserver/...
