From 1075562c9e34153b43c12ec5c0b173a1a593b92a Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Wed, 8 May 2013 12:27:26 -0400 Subject: mkfs.ubifs: allow reformatting of devices Sometimes I want to re-initialize an existing ubifs, but the tool currently bails out if the volume is already formatted. Prompt the user instead so they can decide.
