I actually re-started the discussion about that (about the third time) a
few days ago on https://lists.ubuntu.com/archives/ubuntu-
devel/2016-April/039302.html . This is actually another point in favor
of moving to location based USB names by default.
@Andres: For the time being, please see
I pinged pitti on IRC earlier today, and just subscribed him for
guidance on whether this can be fixed in systemd; which seems to be the
least intrusive way to handle this (aside from expecting users to know
about this limitation and renaming interfaces themselves).
** Changed in: iproute2
This isn't a simple problem at all.
The new naming scheme from systemd makes it so that these specific
devices (USB dongles) get their MAC address encoded in the device name,
which brings it up to a length of 15 characters + \0; so 16 bytes. This
happens to also be the size limit for interface
ifupdown handles the passed names correctly, but it looks like iproute2
is very unhappy about something in these long names like
"enx000be608397d:1"; when setting the label for the address. Since the
label must match the device and it otherwise works with "eth1:1", I'll
looking into the iproute2
Looks like at first glance ifupdown is confused by this naming format
together with the subif. I'll try to reproduce here, I do happen to have
a USB ethernet dongle that should show this problem.
