Hi Andrei,

chown root:root / 

fixed both this issue and my need (today, as discussed in my other email) to 

modprobe tun

to be able to run VMs with virt-manager.

That was a new problem I only noticed today when setting up a VM to find/grep relevant strings/filenames that would exist in a new installation.  I use VMs more often than who/users but have certainly done both without issue since setting up / on ZFS.

But worth bearing in mind :)

Thanks
Gareth
