[lxc-users] short question: can a user know he is inside a container ?

[David Shwatrz]

Hello, lxc users,

Is there a way for a user who is inside some shell in a container
to know that he is inside a container? I am not talking about setting
specific different host names to containers, but the question is: is
there something general/inherent to containers,  which indicates that
a user is  inside a container ?

Best,
DavidS
