I have a bunch of VBox Linux VMs (CentOS 6/7, Debian7/8/9, Ubuntu
(14.0/16.04, Alpine) that get dynamic IPs. To get their respecitive
IP addresses I have to login and run 'ip addr'
I would like such info to be displayed on the VM console *before* the
login prompt. Ideally an ASCII log + info (see below sig line).
Thus, I can get the info from the VM console without having to login.
I read up on /etc/issue but adding "\4{eth0}" to the existing string
does not work.
TIA for solutions/pointers
