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.
