One suggestion I have for the installation process- on this old emachines M6809 notebook, I had three partitions- Windows XP, Lubuntu 17.04, and Vector Linux LIGHT 7.1, and unallocated space of about 15GB for installation of VL 7.2 x64 RC2.
I started the installation, and chose 'automatic' for the disk & partition selection, thinking that it would figure out that three partitions are in use, and there's unallocated space, so it will use the unallocated space by default, right? But NOooooooo..! the VL install wiped out all the other partitions and created one partition for the OS, much as you'd expect Windows to do.
Now, it's no big deal- I didn't have anything important in those other partitions. I just think that the installer, when evaluating the existing partitions, should use the unallocated space for the current install and leave existing partitions alone; in other words, the user might not be aware that an 'automatic' installation will destroy his existing partitions. To me, the OS install should DO THE LEAST DESTRUCTIVE THING BY DEFAULT. Or at least warn the user just before partitioning that the option he chose will wipe out all partitions on the disk for the current install.
