I had segfaults on nwipe on window resizes, hopefully that will help.

This is so i can add "installation" instructions after I figure out
how to rebuild fallax.

this allows us to move blockdev instances.

also retroactively update the limit in gnt-chi to reflect the actual
value there.

This way it can be split in multiple sections without getting in the
dreaded "heading level 4". We kept a cross-reference.

Those were interpreted as LaTeX math formulas by Gitlab's markdown...
