Linux world for quite a while, and this is the first time I ran into
this situation.
Yes. Other distros let you choose which partition gets reformatted. My installs of Fedora
have been on systems with Windows installed, where I shrink the Windows partition and
use the free space, or installs to new disks where I don't do any preparation, just run the
installer. Recently, however, I installed Fedora on an SSD pulled from a Windows system
and hit the "no space" issue. I just removed the existing partitions with Disks in the Live
System and ran the installer again.
