- Show free space of currently mounted partitions. Should help with
people running out of free space and ending up with non-working

written FreedomBox images to higher capacity SD cards. Very selective
and restrictive checks to minimize problems.
- Automated tests to ensure expansion works in non-trivial senarious.
