I've been caught out before when installing Linux with
existing data on several partitions, and had my partitions
and data trashed. My work around is to only let the
installer use / tmp and swap. That way it cannot touch my
partitions with data on them.
Once the initial installation is completed I then install my
own /etc/fstab from backups. This then allows the new Linux
OS to mount those partitions with existing data on them.
