It's a test box. Occasionally I want to compare a default to an optional.

It's a test box. It's easier to delete unwanted common parameters than to 
remember
the names and add them in when needed. vga= is fallback better than 80x25 when 
KMS
is broken. video= is better than booting first, then reconfiguring console font,
then booting again to enjoy legible vtty text. radeon disable/amdgpu enable is
required on Sea Islands when amdgpu DDX is wanted.

No such problem in Tumbleweed:
