Hi folks,

From the better-late-than-never dept...

The xfsprogs repository at:

    How does moving executables to /usr/sbin pertain to cleaning
metadata?  What happens if /usr is not mounted or not created
and the user is running the xfs utils out of /sbin??  For that
matter, if the tools are run out of /sbin, are you saying xfs_scrub
will move them all off of the root partition onto the /usr partition?

    If you are moving the executables, are you also moving all of their
linked libraries?  It seems if you are wanting safety, moving the libraries
and executables to the same directory would be prudent, otherwise,
why move them to to /usr/sbin?

What is libxfs being merged with?

Thanks!

I think we have a misunderstanding here.  "Move all executables" means I
changed where the xfsprogs package puts the binary when installing the
package.  xfs_scrub does not itself move binaries (or any file) around
when it is running.

The reason for changing the packaging is that xfs_scrub depends on
libraries in /usr, so it makes no sense to have xfs_scrub in /sbin.

If /usr is broken and won't mount, use xfs_repair to make it mountable,
just like we have always done.

xfs_scrub is only meant to be used as a background process on a system
once it has come completely up.  xfs_repair's role has not changed -- it
is still the intended tool to fix filesystems that will not mount or
that cannot be fixed while online.

No.

Merging bug fixes from the kernel into xfsprogs.

	That people/projects have moved utils or the libs needed
to mount, repair or restore, a /usr partition has been one of
my ongoing concerns. 

Thanks for clarifying & cheers!
