List the LVs in a guest:
Disable autosync. This is enabled by default. See the discussion
of autosync in the L<guestfs(3)> manpage.
+=item B<-r> | B<--ro>
+
+This changes the C<-m> option so that mounts are done read-only
+(see C<guestfs_mount_ro> in the L<guestfs(3)> manpage).
+
=item B<-v> | B<--verbose>
Enable very verbose messages. This is particularly useful if you find
vgcreate VG "/dev/sda1 /dev/sdb1"
+=head1 COMMENTS
+
+Any line which starts with a I<#> character is treated as a comment
+and ignored. The I<#> can optionally be preceeded by whitespace,
+but B<not> by a command. For example:
+
+ # this is a comment
+ # this is a comment
+ foo # NOT a comment
+
+Blank lines are also ignored.
+
+=head1 RUNNING COMMANDS LOCALLY
+
+Any line which starts with a I<!> character is treated as a command
+sent to the local shell (C</bin/sh> or whatever L<system(3)> uses).
+For example:
+
+ !mkdir local
+ tgz-out /remote local/remote-data.tar.gz
+
+will create a directory C<local> on the host, and then export
+the contents of C</remote> on the mounted filesystem to
+C<local/remote-data.tar.gz>. (See C<tgz-out>).
+
+=head1 EXIT ON ERROR BEHAVIOUR
+
+By default, guestfish will ignore any errors when in interactive mode
+(ie. taking commands from a human over a tty), and will exit on the
+first error in non-interactive mode (scripts, commands given on the
+command line).
+
+If you prefix a command with a I<-> character, then that command will
+not cause guestfish to exit, even if that (one) command returns an
+error.
+
=head1 COMMANDS
=head2 help
=back
+=head2 echo
+
+ echo [params ...]
+
+This echos the parameters to the terminal.
+
+=head2 edit | vi | emacs
+
+ edit filename
+
+This is used to edit a file. It downloads the file, edits it
+locally using your editor, then uploads the result.
+
+The editor is C<$EDITOR>. However if you use the alternate
+commands C<vi> or C<emacs> you will get those corresponding
+editors.
+
+NOTE: This will not work reliably for large files
+(> 2 MB) or binary files containing \0 bytes.
+
@ACTIONS@
=head1 ENVIRONMENT VARIABLES
Set the path that guestfish uses to search for kernel and initrd.img.
See the discussion of paths in L<guestfs(3)>.
+=item LIBGUESTFS_QEMU
+
+Set the default qemu binary that libguestfs uses. If not set, then
+the qemu which was found at compile time by the configure script is
+used.
+
+=item LIBGUESTFS_APPEND
+
+Pass additional options to the guest kernel.
+
=item HOME
If compiled with GNU readline support, then the command history
is saved in C<$HOME/.guestfish>
+=item EDITOR
+
+The C<edit> command uses C<$EDITOR> as the editor. If not
+set, it uses C<vi>.
+
=back
+=head1 EXIT CODE
+
+guestfish returns I<0> if the commands completed without error, or
+I<1> if there was an error.
