[systemd-devel] systemd-nspawn network interface name collisions

[Florian Koch]

Hi,

if i understnd this correct, the network interface names (veth and
macvlan) are created with the frist 11 Caracters from the
Containername (Machinename).

Now if you use similar names for conatiners, like

com.$company.$devision.$name1
com.$company.$devision.$name2
com.$company.$devision.$name3

the network device name handling is broken.

I tryed to prefix the machinename with a uuid (uuidgen) but the the
names are to long.

Why not using a 11 Caracter uuid / random  for network interface
names, and avoid all the naming trouble?


regards Florian
