I did a similar test a couple of months ago, albeit on a smaller system, and 'only' 10,000 users. I saw a similar delay at boot time, but also saw a large amount of memory utilisation. > So ... how about an automounter? Is this even possible? Does > it exist ? Around the same time, Casper Dik mentioned the possibility of automounting zfs datasets, as well as the possibility of cool stuff like *creating* zfs datasets with the automounter. One thing that hasn't been touched on is how one would back up a system when some (or most) filesystems are unmounted most of the time. Is is possible to make a backup and/or take a snapshot of an unmounted dataset (and if not, is that a future possibility)?
