I think you should use Dev_or_Path here. See for example
daemon/stubs.c:file_stub and daemon/file.c:do_file.
Perhaps Dev_or_Path doesn't do the right thing, but in that case we
should improve it, instead of just making things untyped.

mount_local and do something, and then I met busy umount.

mount_local and do something, and then I met busy umount.
That could be a different problem. The way to unmount
guestfs_mount_local is either: guestfs_umount_local or calling
'fusermount'.
http://libguestfs.org/guestfs.3.html#guestfs_umount_local
https://github.com/libguestfs/libguestfs/blob/a58368b3db4f02b9fd907cec826...
(Don't confuse mounts on the host with mounts in the appliance.)

Can we call this macro:
STRDUP_RESOLVE_DEVICE_OR_PATH
I think that would be more descriptive. Also this comment would
be better:
/* Same as REQUIRE_ROOT_OR_RESOLVE_DEVICE but this strdup's the result. */
Otherwise the patch seems OK.
You can delete the following files from your local repository, and
that will stop them from polluting these patches ...
+daemon/errnostring_gperf.c
+fish/cmds_gperf.c
+gobject/src/optargs-add_drive_opts.c
