Niko and Dom came up with this recipe:
# unshare -n
# ip li set lo up
# ip li add dummy0 type dummy
# ip li set dummy0 up
If you are using pbuilder/cowbuilder you can
- make sure you have USENETWORK=no in your pbuilderrc
- add the following to /usr/lib/pbuilder/pbuilder-unshare-wrapper
after the lo dance:
ip li add dummy0 type dummy
ip li set dummy0 up
Cheers,
