jail -- ps: bad namelist - no kernbase

[Pierre-Philipp Braun]

Hi,

I'm trying to run a jail guest and I'm experiencing a little issue.  I 
can't ps,
    ps: bad namelist - no kernbase
nor ping,
    ping: socket: Operation not permitted

I installed it manually using cpdup (without any options) against 
memstick's content (same one I used to install the jail host: x86_64 
2.8.2).  Enabling procfs in the guest didn't help.  There's no device 
files appart from log, null and random but guests's dmesg says it's 
mounting devs.  I don't have any /etc/fstab but I don't think that's an 
no-no since I can see the and walk into the tree (root on / hammer). 
I'm running the default kernel.  Any help?

Thanks
