The mult_mount test creates a small disk image, formats it, and mounts
it in multiple locations in preparation for the tests. However, the
created raw file (80KB) is too small to make a working file system if
4K blocks are used by mkfs. In Ubuntu 19.10, the default was recently
changed for mkfs to default to always using 4K blocks, causing the
script to fail.
We could force mkfs to use 1K blocks, but instead, in case some future
version of mkfs decides not to support 1K blocks at all, we bump up the
size of the disk image to 512KB; large enough to work with 4K blocks
yet small enough to be workable in small scale test environments.
