Describe the bug

NixOS 19.09 panics when starting the installer:

Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

Then select Linux Installers, Select NixOS, Select 19.09.

Expected behavior

The installer should boot.

Ah, turns out this is caused by low RAM! -m 4096 lets the system boot. Disregard me.
