[lxc-users] old Ubuntu 8.04 container, /sbin/init fails

[jf]

Thanks for the help.
So what I miss is how to debug /sbin/init in a container ?
I saw that lxc-start has an extra argument to execute the init command like
lxc-start -n container /sbin/init.
But I'm using lxd and didn't find any equivalent command for lxc start.
