Subject: [PATCH] Prevent common cross-debootstrap newaliases issue.
While building target images for a different arch (using qemu-user-static),
the following issue prevents the succesful image build:
newaliases: fatal: inet_addr_local[getifaddrs]:
getifaddrs: Address family not supported by protocol
For more information, see [1].
