Thanks. Though, reporting "disk is full, remove partitions so that I can
use more space in the DOS label" is much better than corrupting your data
but still not optimal.
For extra bonus points, it could tell the user that disk space is being
wasted, and that replacing the DOS label with a GPT one would resolve that,
at the cost of losing all data.
Since the typical situation in which this happens is a user migrating from
Windows to Debian, this would make a nice example of what a real OS looks
