As far as I can see, the workflow of the test is to reformat the existing file
system by using the forcing option of mkfs tool (for example, -F of mkfs.ext4).
And, then, it tries to reformat the partition with existing file system (ext4,
xfs, btrfs, etc) by HFS/HFS+ mkfs tool with default option. By default, it is
expected that mkfs tool should refuse the reformat of partition with existing
file system. However, HFS/HFS+ mkfs tool easily reformat the partition without
any concerns or questions:
sudo mkfs.ext4 /dev/loop51
mke2fs 1.47.0 (5-Feb-2023)
/dev/loop51 contains a hfs file system labelled 'untitled'
Proceed anyway? (y,N) n
sudo mkfs.ext4 -F /dev/loop51
mke2fs 1.47.0 (5-Feb-2023)
/dev/loop51 contains a hfs file system labelled 'untitled'

It looks like we need to modify the HFS/HFS+ mkfs tool to refuse the reformat of
existing file system and to add the forcing option.
Adrian, How does it feasible such modification?
Thanks,
Slava.
