+I<-c>, I<-d>, I<-i> and I<-m> open disk images read-only or for
+writing.
-In libguestfs E<lt> 1.6.2, guestfish and guestmount defaulted to
-opening disk images supplied on the command line for write. To open a
-disk image read-only you have to do I<-a image --ro>.
+In libguestfs E<le> 1.10, guestfish, guestmount and virt-rescue
+defaulted to opening disk images supplied on the command line for
+write. To open a disk image read-only you have to do I<-a image --ro>.
This matters: If you accidentally open a live VM disk image writable
then you will cause irreversible disk corruption.
-By libguestfs 1.10 we intend to change the default the other way. Disk
-images will be opened read-only. You will have to either specify
-I<guestfish --rw> or change a configuration file in order to get write
-access for disk images specified by those other command line options.
+By libguestfs 1.12 we intend to change the default the other way.
+Disk images will be opened read-only. You will have to either specify

+write access for disk images specified by those other command line
+options.
-This version of guestfish has a I<--rw> option which does nothing (it
-is already the default). However it is highly recommended that you
-use this option to indicate that guestfish needs write access, and to
-prepare your scripts for the day when this option will be required for
-write access.

=head1 WINDOWS PATHS
If a path is prefixed with C<win:> then you can use Windows-style
-paths (with some limitations). The following commands are equivalent:
+drive letters and paths (with some limitations). The following
+commands are equivalent:
file /WINDOWS/system32/config/system.LOG
- file win:/windows/system32/config/system.log
-
file win:\windows\system32\config\system.log
- file WIN:C:\Windows\SYSTEM32\conFIG\SYSTEM.LOG
+ file WIN:C:\Windows\SYSTEM32\CONFIG\SYSTEM.LOG
+
+The parameter is rewritten "behind the scenes" by looking up the
+position where the drive is mounted, prepending that to the path,
+changing all backslash characters to forward slash, then resolving the
+result using L</case-sensitive-path>. For example if the E: drive
+was mounted on C</e> then the parameter might be rewritten like this:
-This syntax implicitly calls C<case-sensitive-path> (q.v.) so it also
-handles case insensitivity like Windows would. This only works in
-argument positions that expect a path.
+ win:e:\foo\bar => /e/FOO/bar
