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
