Here is an example using the new 'shwh' (show-whiteouts) option,
available in aufs-20080310.

Maybe you'd like to check this through and include it in the cvs source?
# EXAMPLE USAGE OF THE 'shwh' OPTION -- 2008.03.11 #
I am always wondering about converting to /proc from /sys. Some people
told me that newer system should select sysfs. But the changes of sysfs
interface is painful. How do you think about procfs and sysfs?
If I may join your debate, I have a suggestion for AUFS. I always wondered why

Well it depends, if the sysfs files for brs are supposed to mimic the
/proc/mounts interface, why not use /proc/mounts for it? There's the
- -show_options callback now that should work perfectly for that,

Here's the updated patch. The old one compiled but had a few stupid
merge errors left in it that caused it to bail out early after reading
the inode. This one works as expected.

Because /proc/mounts has a size limitation.
Some aufs users had met this limitation and I developed
/sys/fs/aufs/brs.
What's the limitation? It uses seq_file, and passes the seq_file handle
to -show_options.
The maximum size of seq_file is PAGE_SIZE by default.

Tomas M:
And after then, information for every fuse-mounted filesystem appears there.
So it seems to me FUSE doesn't like sysfs as well, and thus it implements a
workaround by using a different 'virtual' filesystem.
So you could perhaps do the same for aufs?
Thank you for your
Jeff Mahoney:
Yeah, that's what I was saying. A regular seq_file will expand, but
since -show_options is called from within another -show operation, it
can't.
As far as I know a regular seq_file doesn't expand automatically.
Will you point me why do you think so?

The real cause was NOT in aufs (or unionfs), but in squashfs, more exactly
due to the LZMA compression, more information in

It seems that debian people failed to apply sqlzma patch for squashfs,
