Public bug reported:

testcase: "Install (erase and re-install) in Ubuntu Desktop amd64 in
Kinetic Daily "

The test is supposed to check that the /home filesystem has been wiped.
I do not know if the new install is supposed to have a dedicated /home
partition too. Note that the corresponding but that I encountered has
existed since at least 20.04; I'm not sure when was the last release
with a proper behaviour and therefore I cannot work backwards to
describe that behaviour.

Currently the test "passes" because the new installation doesn't use a
dedicated /home partition and re-uses the / one ; therefore the new
install cannot use the one that had been used by the first install.
Since the test criteria is only that files created before are not
visible anymore, the test is marked as passed while it should fail.

Improvements:
- after chosing to re-install, the installer displays what will be done to partitions: this should include formatting the previously-used /home partition (which requires remembering the partition numbers seen when partitioning for the first install),
- check that 'df -h /home' outputs a 'mounted on' and a 'size' that match what is expected,
- sudo 'fdisk -l /devb/sda' (or the appropriate disk, as used when doing the first install) and check that if a dedicated /home partition is not used by the second install, then the old /home partition has been removed,
- if the new system isn't configured to use a dedicated partition, then try to mount the previous /home partition and if it doesn't fail, then 'ls' it to check that it is empty.
