Bug#504678: add -r to make resulting devices read/only

[Wakko Warner]

Package: kpartx
Version: 0.4.8-13
Severity: wishlist
Tags: patch

I'd like to have the ability to create targets in which are read-only to
keep from accidentally modifying the newly created device.  In some cases,
mounting with -o ro still modifies the device (in the case of ext3
filesystems).  I created a small patch that will do this.  I have tested it
only to the point that using -a with or without -r produces the desired
effects.
