Util-linux package, at least as far back as version 2.23.2 as found on
CentOS 7, provides the mkfs.minix and fsck.minix commands. Also blkid
from the same package, recognises minix file systems.
Create version 3 file systems because MINIX 3 [1] is the only supported
version and that reportedly uses version 3 of the file system [2].

"MINIX 3 uses Minix File System (MFS). More precisely MFS V3."
Closes!12 - Add minix file system support
Add support for detecting UDF file systems and formatting hard disks
with revision 2.01 UDF file systems using udftools. Formatting optical
disks or any other media types is not supported yet. Changing label or
UUID after formatting is not supported as the tools do not yet exist.
