Package: ifupdown
Version: 0.7
Severity: critical
Justification: breaks the whole system

Dear Maintainer,

After an upgrade of the system the ifup command doesn't recognize anymore the aliases for the VLANs.
I have severals vlans configured in /etc/network/interfaces like this:

auto eth1.10
iface eth1.10 inet static
address a.b.c.d
netmask 255.255.255.192

auto eth1.10:1
iface eth1.10:1 inet static
# description Malu-rosu
address a.b.c.d
netmask 255.255.255.192

auto eth1.11
iface eth1.11 inet static
# description Armasesti
address a.b.c.d
netmask 255.255.255.192

auto eth1.11:2
iface eth1.11:2 inet static
# description Armasesti
address a.b.c.d
netmask 255.255.255.192

If you want to start the interfaces the ifup -a gives this error:

root@router:/etc/network# ifup -a
Error: argument "10:1" is wrong: id is invalid
Ignoring unknown interface eth1.10:1=eth1.10:1.
Error: argument "11:2" is wrong: id is invalid
Ignoring unknown interface eth1.11:2=eth1.11:2.

Best regards.

I've just committed a fix.

For this:

iface eth2.2:3 inet static
address 3.4.5.6/23

It now runs the following:

if test -d /sys/class/net/eth2 -a ! -d /sys/class/net/eth2.2 ; then ip link set up dev eth2; ip link add link eth2 name eth2.2 type vlan id 2; fi
ip addr add 3.4.5.6/255.255.254.0 broadcast 3.4.5.255 dev eth2.2:3 label eth2.2:3
ip link set dev eth2.2:3 up

Please check if that's correct.

WBR, Andrew
