NixOS has traditionally enabled the `ext` family of file systems by default. Originally, when switching to systemd initrd, we wanted to transition to making this explicit so that initrds could be made without `ext`. The problem is that anyone with `fsType = "auto";` for an `ext` file system in initrd will fail to boot, which is not really an acceptable regression as we switch to systemd initrd by default. By removing `default = "auto"` from `fsType`, we rule out the vast majority of these regressions as eval errors, since most users of `fsType = "auto"` for ext file systems are using it because of the default value. In hindsight, this is probably what #225352 was really about.
