@edsantiago Is this something your man page validation script could catch in the future?

@edsantiago Is this something your man page validation script could catch in the future?

Sigh. The script was designed to catch that, but two subtleties in the way the man page was written:

#### **--image-volume**, **builtin-volume**=*bind|tmpfs|ignore*
                           ^-- no dashes         ^-----^---- or-signs

...made my script ignore that portion. I'm now looking into a way to fix that by being stricter.
