Hm, you are right, my mistake, sorry - it was only /dev/tty1 as real device
others was just files, so only tty1 was working.  Thanks for
clarification.

Yes, yes, that's also my mistake - there is no need for ttys in cgroup
allow as 'lxc.tty' makes pty's

But I'm woundering if there is a good behaviour - if I hadn't configured
lxc.tty I still have ttys but from host. This is confusing, as man
lxc.conf says, that lxc.tty sets a number of existing ttys, and if you
will not set it - agetty will fail, while it does not.

Probably it should be changed into man lxc.conf than (some clarification
about devices) =)

Actually until now I haven't reasised that devices (except ptys) actually are
not virtualised, maybe it also should be noted into man lxc as a big fat
warning - for someone with openvz background it may be very confusing.
What do you thinK?

(And as now i've realized this, it opens some nice advantages =))
