The idea here is to use LVM copy-on-write snapshot feature to reduce disk usage needed for the multiple instances.

1. Create a 300G sparse file. This file will not be using much disk space initially, despite its apparent size.

truncate -s 300G image.img

2. Attach a loop device to the file and grab its name

loop=$(losetup --show -f image.img)

To test:

1. Adjust paths in the configs
2. For the first node, use a copy of an up-to-date database
3. For another node, use a blank database (don't create any) or a database that's missing some ATXs etc.
4. Prepare network namespaces:

   $ sudo ./setup.sh

5. Run the first node:

Subject: [PATCH] ip-neighbor: update incomplete nbr adj entries upon MAC
 change

The rewrite data from the incomplete nbr adj entries is used, for
example, for ARP requests, so it needs to be updated when the
interface MAC address changes.
