6.2beta2 installation on hda (root on hda5)
6.0 installation on hdb (root on hdb8), to upgrade
At the 'Upgrading your system' screen, I selected 'hdb8' to upgrade, but I
get an error dialog:
Error mounting hda8: Invalid argument
It looks like the installer has muddled the two disks up.
This issue is resolved in the latest cut of the installer.
