thank's herbert for your hint.
hopefully, enrico is listening.... ;)

this is not possible due to our setup (there are two drbd-devices where
the vservers reside on. it must be possible to remove one of these
drbd-devices).

> b) unmounting the filesystem in _all_ namespaces
how could we achieve this? we were reading a lot of documentation
regarding this and vnamespace, but it seems that there is no easy way of
removing all unreachable (out of the chroot path) devices in a given
namespace.(?)

enrico, we read your talk with sam and others in november '04 but didn't
get any hints about the current status. is there any way of cleaning up
a new namespace in the pre-start-script or generally for all namespaces
available?

at the moment, we are playing around with the pre-start-scripts, until
now unsuccessfully...

best regards
lukas.
