[Pkg-vsquare-devel] Bug#418065: vde2: integration with ifup/ifdown needlessly restrict the naming of the interface

[Raphael Hertzog]

Package: vde2
Version: 2.1.6-1
Severity: normal

The scripts /etc/network/if-pre-up.d/vde2 and
/etc/network/if-post-down.d/vde2 won't do anything if the interface name
doesn't match "tap*".

The goal is probably to avoid messing with real already existing
interfaces but it has the bad side-effect that it prevents me from naming my
tap interface following my wishes. 

For instance, I wanted to name my tap interface "qemu" because I was
planning to use it as switch between the various qemu virtual machines.
I removed the check:
case $IFACE in
    tap*)
        # Remainder of script.
    ;;
    *)
        # Not a tun/tap device.
        exit 0
    ;;
esac

And afterwards my qemu entry in /etc/network/interfaces worked:
iface qemu inet static
    address 10.0.2.1
    netmask 255.255.255.0
    vde2-switch -
    up /etc/init.d/dnsmasq restart || true

If the goal was to avoid messing with real interfaces, you should rather rework
the test based on the output of "iconfig -s -a" or something similar.
