Comment 1 for bug 1843659

An additional remark.
ZFS will change the ways we deal with multi-boot situation, since it will be relatively simple to add or delete a Linux OS. You do not have to reorganize all your partitions.
Currently I use VMs to test/try new versions of the Ubuntu flavors, however for 20.04 I consider to use real hardware to try out those development editions. ZFS would make that relatively simple, just add a few datasets. If the Beta is finished you can delete those again :)
