Testing Done: Tested squashing of interfaces with multiple iface stanzas
This is controlled by ifaceobj_squash config variable in
/etc/network/ifupdown2/ifupdown2.conf.
With ifaceobj_squash=1, ifquery and all commands will
output squashed interfaces.
$cat /etc/network/interfaces
auto swp3
iface swp3
mtu 9000
auto swp3
iface swp3 inet static
address 10.0.17.3/24
auto swp3
iface swp3 inet static
address 10.0.18.3/24
address 2000:1000:1000:1000:3::5/128
$ifquery -a
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet dhcp
auto swp3
iface swp3
mtu 9000
address 10.0.17.3/24
address 10.0.18.3/24
address 2000:1000:1000:1000:3::5/128
When and why do we need this ?
- If we preserve multiple ifaceobjects for the same iface,
it gets tricky in some cases to set default policy
values because the addon module run methods are called
on each ifaceobject.
- Each ifaceobject belonging to the same interface
is treated as a separate interface. It is difficult
to remember things accross addon module run methods
- we have a few hacks in place which we would like to
get rid of
Why not turn it on by default ?
- still debating about it. Dont want to break existing
scripts with change of output. Will get some feedback before
I switch the default to squash.
