names, you will need to locate and parse the password file
yourself (Augeas support makes this relatively easy).
+=item $output = $h->command (\@arguments);
+
+This calls runs a command from the guest filesystem. The
+filesystem must be mounted, and must contain a compatible
+operating system (ie. something Linux, with the same
+or compatible processor architecture).
+
+The single parameter is an argv-style list of arguments.
+The first element is the name of the program to run.
+Subsequent elements are parameters. The list must be
+non-empty (ie. must contain a program name).
+
+The C<$PATH> environment variable will contain at least
+C</usr/bin> and C</bin>. If you require a program from
+another location, you should provide the full path in the
+first parameter.
+
+Shared libraries and data files required by the program
+must be available on filesystems which are mounted in the
+correct places. It is the caller's responsibility to ensure
+all filesystems that are needed are mounted at the right
+locations.
+
+=item @lines = $h->command_lines (\@arguments);
+
+This is the same as C<$h-E<gt>command>, but splits the
+result into a list of lines.
+
=item $h->config ($qemuparam, $qemuvalue);
This can be used to add arbitrary qemu command line parameters
See also C<$h-E<gt>is_file>, C<$h-E<gt>is_dir>, C<$h-E<gt>stat>.
+=item $description = $h->file ($path);
+
+This call uses the standard L<file(1)> command to determine
+the type or contents of the file. This also works on devices,
+for example to find out whether a partition contains a filesystem.
+
+The exact command which runs is C<file -bsL path>. Note in
+particular that the filename is not prepended to the output
+(the C<-b> option).
+
=item $autosync = $h->get_autosync ();
Get the autosync flag.
