Thanks for the reply Rich!

I’m not exactly sure what is meant by LVM type.  If I look at the wikipedia  
page on devicemapper (https://en.wikipedia.org/wiki/Device_mapper) it lists  
a number of “mapping targets” - are these the LVM types?  If it is, we’d be  
looking at linear mapping.

The broader objective is to have a system with multiple root filesystems on  
a 16 GB EMMC device, and be able to add/remove/resize additional  
filesystems using the LVM2 userspace tools, much like a typical binary  
desktop distro would configure your hard drive.
