Hi Dave,
I have searched the internet according to the information you provided,
I find this bug report <https://github.com/lxc/lxc/issues/250> provides useful information.
I have written an example program after going through the clone(2) man page.
It demonstrates the problem and is inlined below.
First, compile the program as `a.out'.
Consider shell session 1:
root# echo 0 > /proc/sys/kernel/unprivileged_userns_clone
user$ ./a.out
I am your parent
Start cloning...
Cannot clone!
Consider shell session 2:
root# echo 1 > /proc/sys/kernel/unprivileged_userns_clone
user$ ./a.out
I am your parent
Start cloning...
Cloned!
I am your child
Any idea what's happenning?
I don't know Linux much, for instance I don't know what is container and namespace in Linux.
Thanks!
Cheers,
Alex
